Cervelo One
Our goal with the One is to create the ultimate entry-level triathlon bike while maintaining the highest quality standards. The 2004 One will still offer the tried, tested and TrueAero frame of Ironman winning pedigree but it will be coupled with a Shimano 105 kit containing all the components you need for your first few years in triathlon as well as an STI shifting set-up and full-blown aerobars.
It is also important to note that the correct NACA profile is not round at the front but eliptical. Aerotubes with a round front and sharp trailing edge are becoming more and more popular (because it they are easy to make out of a round tube, and because they will easily take a round seatpost if used as a seattube). But unfortunately they offer hardly any aero benefit, as the bluntness of the round front already deflects the airflow before it reaches the trailing edge
NOTE: All our TT/triathlon bikes have a dropped toptube and shortened headtube to enable the rider to position the aerobars low enough for a proper aero position. This means that a frame measures smaller from the bottom bracket to the top of the seattube than it actually is and than the size would indicate. So the size is a virtual measurement, and all it means is that if you ride a 54cm road bike you'll likely need a 54cm TT/triathlon bike as well. But since all manufacturers use different geometries, this doesn't always pan out exactly either.
- The same tubeset that won Ironman Canada in 1999, but with updated geometry tailored to the novice triathlete
- TrueAero downtube as found on the P3
- ICS (Internal CableStops), the best internal cable system available
- 75 degree seattube angle for aerodynamics and bike control
- Dropbars and STI for control in all riding positions
- Wheelsize (650c or 700c) optimized for each size for proper rider positioning
