C-C means centre to centre
Refer to the second and third columns above to see what size we recommend.
Some features of the geometry are
- coverage of people over a large height range. 150 cm to over two metres.
- use of a smaller wheel diamater on the XS size thereby allowing a short top tube and an unchanged head angle and fork rake. Normally small sizes have the front wheel too far out so as to clear toes. This is all much easier with a slightly smaller wheel.
- bottom bracket heights that are relatively low, making the bikes very comfortable and easy to ride. Higher bottom brackets are more typical on competition (including cyclocross) bikes.
- 450mm length chainstays (430 on XS which has smaller wheels) to give heel clearance from panniers.
There are several subtleties in the frame specifications. One example is that the three larger frame sizes have very slightly thicker walls on the top and down tubes (than on the smaller three sizes). This gives added stiffness to big frames . Another is that, although the bikes are set up with front disc brakes, it is possible to use front cantilever brakes because there are pivots on the forks and a cable hanger is supplied. This is quite reassuring if you are on a long tour as it gives you a back up system.. There are mounts for spare spokes under the left side chainstay. There are lighting cable mounts to keep the wires (which are in sheaths) tidy and to comfortably survive if the bike is packed for plane travel multiple times. |
