Colnago C68 Gravel
2023 · 700c wheels · 5 sizes
Modular carbon gravel race frame. Colnago quotes a maximum tyre width of 42 to 45 mm depending on the build. Colnago names each size by its seat tube length in millimetres. The numbers come from Colnago's geometry sheet; its bottom bracket to front axle figure is a direct diagonal measurement, so it is not listed here as a horizontal front centre. Colnago's website table shows a different head tube, head angle and bottom bracket drop for the 450 size; the geometry sheet values are used here as they agree with that size's stack and reach. On the 570 size the published top tube, front centre and seat angle do not quite line up with its published stack and reach. Stem, bar and crank figures are from the SRAM Force XPLR build.
