Ive had a magura hydraulic rim brake before so not looking to go down that route.
Out of interest, why? By far the most powerfull rim brakes as long as you don’t try an use lightweight XC rims with them..
Adding a brake booster can make quite a big difference on older frames, too.
+1, although older Cannondale frames are brilliantly/brutaly stiff depending on your preferance.
XTR with the parralelogram were more consistent than the normal XT ones (and single digits etc), but both were equaly powerfull when first set up, and seeing as pads rarely lasted into double figures of rides, especialy in winter when 2+ sets in a ride wasnt uncommon, the drop off in power at least gave you some warning before the metal bits hit the rim!
Cartrige pads are a must though, and ceramic rims if you can still find some.
