Dear Forum,
disc breaks are dead? I wish!
These particular ones have a very significant problem. Everytime I use the front break to break stongly, the wheel gets misaligned so badly that the breaks rub and squeal like hell. I mean it's so bad that you can see the tyre is visibly closer to one fork blade and the bike no longer tracks straight. I then need to open the QR and pop the wheen back into both drop outs.
Any ideas why this is? It's as if the skewers don't grip and the disc break just levers the wheel out of alignment. I tried different front wheels, different skewers, tightented the skewers with all the power I have and religned the calipers 1000 times (but it's clearly nothing to do with the caliper alignement, it's the entire wheel).
I'm thinking the dropouts are somehow too slippery. The fork is an early Surly Karate Monkey, the hub is a new SP dyno with industrial bearings, so no movement from there for sure. The rotors are 180mm, calipers are Magura hydraulics. See pics. One also shows the drop outs with the skewers removed.
Is this a known problem with Surly forks? The dropouts not knurled enough? Are the skewers too weak? Should I ditch the damn discs and get a nice set of V's?
Help me please! Thanks!
