So I have nearly finished building a Canyon CF SLX frame with full Dura Ace 7900, including pedals and C24 wheels, and top line finishing kit. It weighs about 6.6kg, stiff and generally superb!
My one sticking point is brakes. I have a set of Dura Ace but I am not convinced by them (relatively heavy at 294g and don't quite live up to the reviews IMHO). Now I am not quite a weight weenie but want something light.
TRP979EQ (not that I can afford them!) or 970SL, Dura Ace, KCNC CB1, Planet X, Superlight Accura?? However, stopping power is something that I think is essential on a bike so reluctant to go for a light low performer.
For info: C24 have aluminium braking surface.
