people consider bicycle fitting to be a mysterious topic, due to the infinitely variable factors that can influence how a person is able to sit on a bicycle. In my mind there are three main

three variables eventually cause an outcome of infinity by the power of 3.
Bike Fitting History
quick history on bike fitting
the mid 80’s there were no official bike fitters, that used a specific system to determine the perfect fit for a human being. Back then good old bike shops were operated and owned by experienced
cycling enthusiasts, rather than todays money oriented businessmen. They would sell the correct sized bicycle, based on experience, and make a quick initial adjustment for their customer, then allow
the user to do the fine tuning themselves.
example: An english tailor is able to eye the appropriate sized piece of clothing for you, an experienced shop owner, would look at a 6 foot person, and determine that a good starting point would be
a 57cm sized frame. Then that person would be able to finalise and tweak their position by themselves, or with the help of a fellow cyclist and coach.
champions back in the day went through the same fine tuning process.
in todays modern society, specialisation has become a trend. Bike shops hire people who know how to use a barcode scanner to sell bikes, but don't even know how to replace an inner tube. I once met a
sport institution rider who would train with a GPS computer, heart rate monitor and power meter, but didn't have a clue on how to oil his chain. Even Dr. Michele Ferrari, the best cycling coach is
come from medical background.
of bicycle frames, often build frames in 4 to 5 sizes, usually with a sloping top tube, to accommodate to the majority of the population while keeping manufacturing costs low, allowing a person to
customise their size further by using various seat posts and stems. Unlike back in the day when a frame builder would have frames that ranged from 48 to 62 cm, providing 15 different stock sizes.
Meaning that today, people will tend to fall between two sizes of frames, rather than finding the perfect one. And to make matters worse, two frames, with the same frame size, may have completely
different geometry. A new 51cm semi sloping top tube frame, is in fact the same as a 54cm horizontal top tube frame. This marketing and inconsistent labeling has caused many headaches with
where variations in frames have decreased, the variation within components has increased to pick up the lost customizability of frames. In the old days seatposts only came in 200mm lengths, with 20mm
setbacks. Modern seatposts now come with 0 - 35mm setback, and up to 400mm in length. Stems used to come in -17 degrees, but now have the capability to come in many different angles and lengths. So
with the modern stem and seatpost, it is possible to fit 99 percent of the population on 4 - 5 sizes. literally all professional riders use stock frames to race this day, with a focus of bicycle
fitting as an aftermarket customisation.
Bike fitting methodology
two main bicycle fitting techniques used in todays industry
Bike fitting systems
design of the first commercial bike fitting system emerged after the mid 80’s. The objective was to create a platform with rigid procedures and protocols. Where a low skilled labourer could
perform the job within an acceptable tolerance for the majority of the population.
earliest bike fitting systems were based on gathering statistical data about the person and their riding positions, then making an estimation on the appropriate frame size, depending upon who that
person was closest to.
advancements in technology, provided more knowledge and greater accuracy about the biomechanical hard points of the human body. Providing a more in depth process of statistical data gathering. Which
means, if you measure a person and all the points on the body, you should technically be able to input this into a software, and through statistical data it would generate your perfect position, and
the bodies relationship between the saddle, handlebar and pedals.
the major drawback to this system is that since it is a calculation based system, it relies on point to point calculation, so if two riders had identical mechanical hard points, height, weight, leg
length, foot size etc but one had a significantly greater fat composition, or was less flexible the outcome would be different. Gathering this point to point data is also extremely difficult, even
with a ct scanner, as the measurements are not underload. And even if you could map all the hard points with 100% accuracy, you would not be able to tell where the tendons are attached to at the
bond, nor do we know the muscles relative strength and nor do we know the riding pattern or technique of that person.
the person from the ruler, and even more factors are introduced, in real riding conditions, the three contact points of the body are not fixed, they are constantly moving and adjusting, moving fore
and aft in the saddle, using different positions on the handlebar, and feet rotating at various angles in relation to the pedal. ie the ball of the foot to pedal spindle relationship constantly
software also relies on point to point protocol as well, Dartfish is
a program where a user can guess the points on the computer screen, it’s much easier to use, but is still not good enough to determine the outcome. However it serves as a good tool for documentation,
meaning I will most likely buy it in the future.
lets say with 0.5% manufacturing tolerances, good for 99% of the population, which leaves 98.5% accuracy, which sounds fairly good. The problem with evaluation software though, is that they are
developed for elite riders, the consumer, does not have that kind of fitness level, condition, skill and technique of a professional rider. Once you begin to consider all these factors in the
formula, the accuracy will begin to drop, so unless your cycling fitness and technique is similar to that of a pro rider, you would get much better results simply by going D.I.Y.
my personal experience, I have re-fit a number of customers who have undergone commercial bicycle fittings before, however they complained about their new position. Normally I find the position close
to their requirements, it just needs small adjustments. The problem seems to stem from their skill and technique, which is what I spend most of the time teaching them, providing them the basis for
making the most from their new position.
2. Alternative bike fitters.
are a new breed of ‘alternative’ bike fitters, in a sense they believe that physical/functional asymmetry + mechanical compensation = functional symmetry and neural function optimization. Basically
this means, to fix issues with bike fitting, you compensate the problem by using simple mechanics, which leads to realignment and therefore a good fit. For example, If your left leg is slightly
shorter than your right leg by 5mm, then you place a riser block under your left shoe, allowing symmetry to be restored. They believe that humans inbuilt automatic ability to re-adjust itself is
inferior and that any patterns of self adjustment done by the body, increases the body's tendency to become more asymmetric. They also ignore the most important neural function: Technique
they set people back 50mm behind KOPS, sometimes 30mm in front, sometimes the saddle is 12mm lower than the neutral position, sometimes 25mm. These random results and actions give the client an
impression that the outcome is not predetermined. They use simple mechanical manipulation to optimize the incorrect riding patterns and poor bio mechanics of their client, which usually produces
instant results. Uninitiated consumers swear by it, and they do have success in their own right, since the body is incredibly adaptable. However it is not only physical but psychological.
law of unintended
at work always and everywhere. The simple intervention in a complex system tends to create unanticipated and often undesirable outcomes. Someone wants the intended consequences of an action so much,
that he purposefully chooses to ignore any unintended effects.
That type of willful ignorance is very different from true ignorance.
are inherent deficiencies with this practice. The main being that the judgement is solely based on the fitter’s subjective observations and confirmed by a kinesiology
then the bike fitter can sell anything to anyone.
the fitter will do is suggest or imply most of the following at the same time, “The stock frame won’t fit, ideally you need a custom frame, you need brand X saddle, brand Y pedals. shims and wedges,
some pedal extension spacers, arch supporters, and a different seatpost, bar and stem” The fitting out come is very likely already predetermined.
Smith wrote " “It is not from the benevolence of the butcher, or the baker, that we expect our dinner, but from regard to their own self interest.”
they are not quite sure what they are doing, and normally they offer a full refund, if the client doesn’t like their un-educated guesswork. Have you ever seen a professional service that would give
you a full refund, if you do not agree with their diagnosis?
have re-fit a few customers that have done this alternative bike fitting, and I usually find that I must make substantial position adjustments and remove most, if not all the products, which they
have brought from their previous bike fitting session, to restore their body to a neutral position.
What is a BikePRO fit?
philosophy, is that a quick fix is the order of modern society, other bike fitters will promise instant results. Our bike fitting does not work that way.
fit coherence and optimize the following:
Technique (neurological function)
Musculoskeletal system (biomechanical function)
Bike setup (mechanical function) in relation to gravity
changes the fact that technique and position go hand in hand.
fit consists of 4 elements.
Remove unnecessary equipment and replace incorrect equipment.
Teach you riding technique and skills.
Long term training with correct technique to develop the correct motor pattern, recondition your body and rebalance your muscles.
we will do, is first teach you how to ride a bike in the correct manner. From there you will begin with a neutral reference point, and learn to develop your own preference or taste. We then use your
feedback and adjust the position according to this. Meaning the outcome is determined by you, not by a 2nd or 3rd parties belief , opinion or certain percential of some historical data.
margin of error will be minimized to a very low level, as nobody knows your body better than yourself. Which means you are able to do the fine tuning yourself later, if you are not 100% assured about
your initial judgement, or if you choose to change your preference later. You are not just part of the process, you run the show!
seems my bike fitting methodology is very old school, but I think it is the only way to achieve the set goals. The greatest challenge is not the fitting itself, it is how to put all the fitting
elements together. But the training part is solely to rely on your dedication and effort. All we can do is to provide a solid platform for you to develop as a better cyclist. It will help to maximize
the return (performance, comfort, general well being) of your investment (money and time that you spent).
don’t sell quick fixes, we provide long term solutions.
What will be done:
Cleat Adjustment ( angular, back / fore & Q-factor
The position of the cleats are very important as it is what locks the foot onto the pedal. We will set the cleats up so that they are suit your specific type
Saddle Adjustments ( height, back / fore
& angular )
Position of the saddle can also be adjusted to suit a specific type of riding. There is more or less a guideline as to what position the saddle should be in
for different types of riding which we will recommend.
Handlebar height / angular, hood position & stem length ( reach )
The handlebar/stem combination is basically the cockpit of the bike. Therefore, we believe that instead of prescribing guidelines, that it must be in a
position that is most comfortable for you. Of course we will make suggestions and recommendations, but this is much a 'trial and error' process until you feel most comfortable. It is a trade off
between comfort & aerodynamic.
Determine Handlebar Width & shape
Again, this is entirely up to you. We'll put different widths & shape on the bike for you to try, until it feels right for you. We will make suggestions
and recommendations, Again, It is a trade off between comfort & aerodynamic.
We have to charge extra to do the handlebar replacement, because it is labour intensive.
Pedaling Technique & Riding Skills
During the fit, we will also explain and demonstrate the correct pedaling technique which best maximizes power output and efficiency. A correct pedaling
style will increase your efficient by as much as 30%. We'll also give advice on your riding skills, which will be specific to how you want to ride. As such, we cater for every type of rider,
from commuters to professional racers.
Are pedaling technique & riding skills that important ?
Without understanding pedaling technique. Someone would generalize the pedaling technique into 3 category.
1. Toe Dipper : Classic example: Anquetil
2. Heel dropper : Classic example: Merckx
3. Average : Classic example: Hinault
They all won Tour de France 5 times, one may conclude that pedaling technique is not a defining characteristic of cycling excellence. Nothing could be
further from the truth!
Their reasons for them to pedal differently:
Cycling shoes' soles were made from thin leather in the 50's. They are not stiffer than the Crocs shoes, so he had to pedal toe down to get more power transfer to the
toe clips/pedals system. The great Fusto Coppi had the same pedaling style in the 40's. However, the general pedaling technique gradually evolved to "average" due to the changing of shoes technology. The
Italians later invented double leather sole shoes & sandwich it with fibre glass.
Anquetil invented the "Anquentil cleat" towards the end of his career in the early 60's. (A cleat with long metal reinforcement). He has changed his pedaling
technique to "Average" since.
"Average" Anquetil in his famous DOUBLE win at the 1965 Critérium du Dauphiné Libéré followed by the 560km Bordeaux-Paris.
TA Anquetil cleat from Andy's collection
The majority of recreational riders who rides with a toe dip is the result of the saddle being too high up, ( the body natural
compensates by extending the ankle as to not cause pain/damage to the knees, hip, and back) as opposed to be by choice. Over a period of time, the body adapts to this position, and becomes
"unconsciously competent" with this pedaling style. That is, you are competent with this technique, without it being a voluntary change that you thought was beneficial. To gain the "average" pedaling
technique, the body won't just simply adapt to a change in the saddle height/position, it also requires training and learning to change pedaling technique.
In 1969, he crashed in a derny-paced exhibition race. A motorcycle pacer and a cyclist fell in front of Merckx, causing Merckx and his pacer to fall. His
pacer, Fernand Wambst, was killed instantly. Merckx was knocked unconscious and was bleeding heavily from a head wound. From this accident Merckx cracked one of his vertebrae and twisted his pelvis.
He admitted in interviews that his riding was never the same after. Because of his injuries, climbing was painful and it may even have limited his winning to some extent. He had to compromise his
pedaling technique, & changed from "average" to heel drop on the bad leg since the horrific accident. Subsequently, Adidas developed shoes with Nylon sole for him. The first modern cycling
shoes, the "Adidas Super Eddy Merckx" with rigid sole was born.
"Average" Merckx in 1968- Paris
In contrast, the heel drop technique is a result of the saddle being too low. This is a result of the body wanting to extend the legs more and hence
'lifting' the ankle up or dropping the heel.The majority of the recreational rider population usually adopts this style due to a few reasons. Again, the become "unconsciously competent" with their
bad technique, and therefore both an adjustment of position and training of pedaling technique is required to alter this.
Andy visited Merckx 1984
Hinault's position & technique was developed by Renault ELF Formula One racing team in the early 80's (his sponsor at the time). They were the first
team to use the dyno (power meter) & wind tunnel for bike fitting & pedaling technique. which was very well documented in the French cycling magazine "Miroir Du Cyclisme". Hinault used "Le
Coq Sportif" cycling shoes, which is a re-brand of the "Adidas Super Eddy Merckx" shoes.
His F1 aerodynamic seat position was more than 2 inches higher than the average 80's saddle height. His torso was dead flat. This was the main cause of his
knee injury, which was also very well documented. Without applying sport physiology into the bike fitting, a pure mechanical manipulation of riding position will never work. Hinault's position
was phased out by the mid 80's, though it did phase in and out a few times after. Without proper sport science, saddle position manipulation was like women's fashion, they come & they
However, the Renault ELF/Hinault's F1 pedaling technique is here to stay, since it generated the highest power output. From the top dead center to lower dead
center/ push phase, it looks like it is the "average" technique, as the feet is dead flat. If you look carefully, the pull phase is not "average" at all! Hinault pulled very hard indeed!
The technique was way ahead of its time. It take almost 30 years for the PRO cycling world to fully adopt it. If you look at the older cycling footage from
youtube, every rider had their own style (best version of themselves), it was almost like a signature. One could identify a particular rider from the distance. With the advancement of modern sport science, all the professional
teams use almost the same method & technique to train. It leveled the playing field. The performance gap between domestic and top riders is a lot narrower these days. It's no longer a well kept
secret how those cycling talents developed. Teams can buy it from ex sport institution personnel.
If youl look at the latest classic & tour carefully, all the tour
riders pedal the same 'not so average' way even under extreme load! Sorry no Toe Dipper, Heel Dropper & set back position.

What is pedaling technique?
What we are talking about here is adapting your technique to a certain situation. There is not one singular style or technique that is best for all aspects
of a ride. In some ways, it is much like the advanced electronic systems controlling car engines today in that the gear selection, valve timing, ignition timing and fuel pluses, or your technique on
a bike, is controlled such that it best suits the situation. Constant real time changes are required, and of course there is a guide as to which 'technique' is best for different
Can pedaling technique be learnt?
Yes. Just like walking, cycling, swimming or playing an music instrument It can be learnt by any person.
Do I need to consciously perform the technique?
The process of obtaining a new skill incorporates several levels of learning and awareness.
Level 1 - Unconsciously
Incompetent (most recreational riders & some bike fitters belong to this category) At this level, the person is unaware of his/her lack of
knowledge or skill in a given subject or task. A person who is unconsciously incompetent is either not aware of the existence/relevance of the skill or they do not realize they are deficient in that
Level 2 - Consciously Incompetent
At this level, the person recognizes there are skills he/she needs to learn, but has not yet addressed the skill deficit.
Level 3 - Consciously Competent
When consciously competent, people can reliably perform a skill without assistance, but it requires a certain amount of concentration and focus on their
part. As they use their newly acquired skill, it will become increasingly automatic.
Level 4 - Unconsciously Competent
At this level people can perform a specific task without conscious effort. The person has had so much practice that the skill has become automatic or second
nature. Some common examples of tasks that often become automatic with practice are driving, knitting, typing, riding a bike, repetitive assembly tasks, etc.
For example, Pilates as an exercise involves conscious control of the movement of each body part, and the proprioceptive feedback to execute a few precise,
controlled repetitions. Unlike Pilates, cycling is high repetition dynamic sport. Proprioceptive feedback mechanism may work under 60rpm in a stationary trainer, It won't work on the road ! The brain
cannot process so much information
When a rider reaches level 4 (unconsciously competent) in regards to their pedaling technique, they do not rely on proprioceptive feedback. Their central
pattern generator can produce meaningful functional output in the absence of sensory inputs (i.e. pedaling has become so much of a pattern that the brain does not have to think/to tell what the leg
has to do). It is quite difficult, once a rider has reached level 4, to pedal with the wrong technique at any load, unless they consciously force themselves to! High performance pedaling
technique is not something that comes naturally to everyone. I stress again that pedaling is not necessarily a natural motion, unlike breathing! It is a skill that needs to be learnt and
We are more than competent to help you to archive this.
Level 5 - Unconsciously perfectly Competent
Though reaching this level may be the ultimate goal, achieving this will take many years of dedication & hard work. This level, is basically the
level World Champions are at.
People avoid complacency and stay abreast of new developments and competency standards. If the "world" changes, unconsciously competent people can quickly
become unconsciously incompetent!
How long does it take to learn?
It takes a few hours to a few days to become "Consciously Competent";
A few weeks to a few months to become "Unconsciously Competent";
and Many years of hard work to become "Unconsciously Perfectly Competent"
Will change of equipment & position affect the technique ?
No, for example, A 178cm rider may use 170mm cranks with higher saddle set up in the track. 172.5mm crank with neutral K.O..PS position in a road race. 175mm
crank with setback position in a mountain bike race. 177.5mm with up front position in a Time trial. If he has reached level 4, he could adapt the different bike settings with different pedaling
styles without further training. He could even ride a bike without a saddle effectively!
Will I need to change equipment to archive a good position ?
In short, no. We are not trying to sell you wedges, shims, different length stems, setback seatposts, weirdly-shaped saddles, weird cleat placement shoes nor
a custom geometry frame. We try to keep your existing equipment as much as possible. Having said that, if some parts need to be changed, we will recommend it to you, with the final decision
ultimately being yours.
Mr X, who is in his mid 50's, had his driver's
license been suspended for a few years. During which time he had been riding to work most days and become very fit. However, saddle adjustments were his daily ritual, as he was not able to find the
sweet spot he had yearned for.

Without changing any equipment, he was all smiles 2 hours later post BikePRO fit.
After BikePRO Bikefit # 2
How much could I gain with proper pedaling & riding technique ?
Without improving any of your physical abilities (ie strength in quads etc), it could improve your efficiency by more than 30%. In turn you could ride harder
& generate more power for the same energy input.

I just wanted to say thank you for your BikePRO Fit. I really appreciate the time you took with me when i was over Melbourne, your technique explanation on my
pedaling has helped so much on so many aspects of my riding. I have been trying to focus on having a three year plan to get somewhere with cycling as I know I still have a lot to learn. When I can

Thank you very much
( 2012 Australia road championship dual bronze medalist )
We did the Italian Triple training ride this weekend, which was 75 miles and 4700 feet of pretty knarly climbs. The first climb is a long grind up Cohasset Road, which I have done three times before,
and the section in the link below is from the start of the cohasset race up the hills to the store (where we turned around; we normally keep going but this one was a long day so we all turn around
there). Oddly enough during the climb I felt good, but did not feel I was doing all that well, but I concentrated on my pedaling technique and keeping my cadence up and consistent, as well as
concentrating on keeping my heart rate close to the peak I can hit without going into the red zone. Amazingly I just loaded the ride in Strava, and I smashed my prior best time by almost 5 minutes
(33:25 vs 38:12).
I can't believe how well I have been doing since having my bike fit session with you!
Of course I am way off the best time of Tim Olson (basically a Pro) who did it in 20 minutes :)
