hi you people
i have just got into trialing and bought myself a handsome dog k9 bike. I have run into a problem with fitting a hs 33 on the back wheel, the brake booster is to small to go over the 2.5 rear tyre. When building the bike i found 2 alu blocks for v's to mount on and another 2 alu block which i think there for fixing the rim brake to it When i fit them to the v mounts with out the booster on it, it just moves the capliers aparts. Here the Picture of the block which i think there for the rim brake but could some tell us if my idea is correct.
thanks
