I'm building a custom Heckler after selling my Jekyll 500 which needed almost every component upgraded. I'm considering a couple of different disc brake setups. I've heard great things about the XT Hydraulics and the 185 mm Avid Ball Bearing Discs. The XT's are slightly higher in price but still within my budget. I'm trying to decide which system to go with. Any thoughts?
easy to service and get parts for
no hydro fluid to mess with, run out of the night before a ride, no bleeding, trailside repairs are less likely to make you walk home.
have to fiddle with knobs a lot
modulation isn't real great
XTs (although I don't own a set)
much lighter than Avids, prolly 2/3- 1/2 the weight
little maintenance to keep working well, no knobs to fiddle with
hydro fluid to mess wtih (trailside repairs can be nearly impossible if something bad happens)
