What say the masses?
Thanks for the replies. I've been doing some research and the crux seems to be the fork (or at least one that's not 600+g) and the combined weight of all the components put together (fork, disc specific rim and hub, higher spoke count, and the disc brake itself) becomes hefty in a hurry. Most front 29'er rims with 100mm hub spacing should work on a CX setup and rims like Enve's 29 XC would probably be fantastic CX wheels - with or without disc brakes. Felt's disc prototype FX2
looks rather interesting and uses 135mm rear spacing for 29er rims, but I still think that a CX bike would do fine with just a disk up front and either a canti or mini-v in the rear; plus I could keep my frame. As the big boys start making disc specific forks and the weight of the entire enchilada comes down it will be a hard fact to ignore that we are using hand- me-down 90's Mt bike technology. I remember when the purists were arguing against Rock shocks :)
Racing aside - I ride my CX bike on more single track than anything else and the idea of being able to scrub speed when things get steep, muddy and the consequences a little more dire than breaking through caution tape is very intriguing. For now I'll stick to my Ultimates (although those mini-v 8.4's look very enticing) and sit back and watch where this disc thing goes.
Happy riding everyone!!
Thanks for the heads-up on rebuilding the disc brakes. I was wondering how they would hold up in the goo compared to their hydraulic big brothers. Maybe that's why TRP's mechanical to fluid conversion thingy is finding its way onto the prototype CX disc bikes.
