So since I really have no experience with either disk brake set; maybe you all can give your opinions on which you might prefer, and why, (of these two) for xc application on a Spec. Epic.
Cost is not an issue, either set is available to me, and it will be one or the other.
Coming from mostly rim brake setups, with a few rides on other's bikes which might have had Disks, a few with Shimano, one with BB5 and another with a Tektro (i think...). They all worked fine, no problems, and really never had the need to get on the limits of stopping on any of those rides. Espescially being on loaner bikes, I'm not about to do anything which might cause issues, so easy does it was the way I rode all the loaners.
But now I get to setup my own toy.
So whats your preference - Hayes Comps or BB7s?
