On a side note how have the brakes been for you? I seem to get a lot of flex within the brake itself which ruins brake feel in my opinion. Does anyone know if i can use the dura ace brakes with sram levers? I guess they would be different ratios?
Or can i adjust them?
I have a 7.9 (6.04kg / 13.3lbs 62cm H2 details will follow) I just swapped my Bontrager brakes for Dura-ace. I hated the bontrager brakes for many reasons, but not for feel funny enough. The Dura-ace brakes work great.
[*] DA were a bit of a pain to install (don't remove the plastic bits before trying to install.)
[*] DA weigh a little less. Front 139g vs 146g. Rear 118g vs 146g
[*] DA front is more powerful than Bontrager (from feel only)
[*] DA rear flexes so I am not sure how much power you could really put in there - but it is a rear brake so I am sure it would lock up before bending too much. Might flex more than Bontrager on the rear
[*] DA is better made with a more quality feel about it and the bolts should not rust (like the bontrager ones were beginning to)
[*] DA pads will be much much easier to swap (important for be with carbon and al. wheels)
[*] DA do not look as stealth as bontrager.
[*] Trek has 3 holes at the front and rear to mount brakes. both brakes use 2 holes. DA and Bont share 1 hole and the other one you pull out a plug from the frame and shift it to the redundant hole.
I hated the bontrager brakes so much for many reasons (mainly build quality, adustability hassles and brake pad swapping hassles. If I had my time again i guess I would buy a full DA setup and not Red/Bontrager for a Trek as the bontrager brakes are a killer for me and I don't like having such a mismatch of red/DA parts.
