Find The Right Size

Cervélos fit better. In the end that is the main reason why they have become the most popular time trial & triathlon bike in history. Of course we have unparalleled aerodynamic know-how, and the frames offer great power transfer and handling. But the most important reason why people are comfortable and fast on Cervélos is that they fit properly.
Cervélo geometry offers two large benefits:

1. It puts the handlebars and saddle in the right position relative to the bottom bracket very easily in its standard set-up, making it easy to find a fast and comfortable position.
2. It offers a very wide range of positioning option thanks to the seatpost design and the different headtube lengths between the P1/P2, P3/P4 and the P5. This allows our customers with a not-so-standard fit to take advantage of Cervélo’s superb aerodynamic and handling performance without any need to go custom.
