Current Projects chat and miscellany

Centaur short cage derailieur, 10spd cassette, amboriso hubs and Araya track rims for the Colnago, it's the skinnest and lightest box section rims I can find frankly;

Track rim and you will be using brakes?

Presumably they have no braking surface and are not built for brakes (wall thickness) which may be why they are light, in the same way MTB disc rims are lighter than the version for rim brakes.

Just make sure you don't use your brakes much :-)
