The Helix OS takes our signature Helix tube set and adds current
component design elements to create one of the most exciting road
race frames for 2011. By adding a SRAM Pressfit 30 bottom bracket
to this frame (which requires BB30 cranks), we have increased
stiffness for maximum power transfer. We have also increased the
headtube diameter for more responsive handling and to accept a Cane
Creek 110 ZS 44mm headset. Our proven Pro Competition geometry can
be found on this top level race frame allowing for an aggressive
riding position. The combination of these features make the Helix
OS the pinnacle of our road racing lineup.
At first glance you will notice the spiral shaped tube design
that adds significant stiffness to the structural integrity of the
tube without adding additional weight. The HELIX shaped tubeset
provides the rider with the highest overall balance of performance
characteristics with the least amount of compromise that you are
forced to expect in many other frame designs.
Different forces occur when braking, accelerating, climbing and
descending. It was our challenge to create a tubeset that best
handles all of these various force vectors and create a harmonious
balance between them with minimal compromise. More force can be
applied to the frame without any loss in pedal efficiency or
sacrifice in performance. Not to mention the unmatched durability
that only titanium can offer. No longer do you have to sacrifice
handling or performance strictly for weight savings.
