| Note 1: | The above headtube lengths are for integrated headsets. To compare to non-integrated headtubes, deduct 20mm from the above lengths to adjust for the stack height needed for non-integrated headsets. |
| Note 2: | All our TT/tri 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 the frame size is no longer equivalent to the seattube length, so don't determine the size that way. Simply go by the size sticker, or measure the headtube and look it up in the above chart. |
