So this one has me stumped. I have recently acquired a Banshee Rune frame (2014). I have built it up and its all gone well, with the exception of the rear brake which doesn't fit properly.
The frame was supplied with 650B dropouts installed but also included were 142mm 26" dropouts and as I have 26" wheels I obviously swapped them over. Unfortunately when installed the rear brake is sitting roughly 3-4mm outboard of the rotor- even with the caliper pushed as far to the right as I can. I have compared the 26" and 650B dropouts and it appears that the brake mounts on the 650Bs are roughly 3-4mm further inboard than the 26". However the 26" dropouts are definitely 142mm as I have measured the distance. What the hell is going on and is this a known problem?
FYI I'm running a Superstar switch evo rear hub but as the gears as nigh on perfect I don't think this is to blame.
Would appreciate any assistance.
You need a different brake bracket adaptor. My shan came with both 650b and 26 dropouts and needed to come with one for each wheel size
The brake bracket adapter came off the old frame which was running QR, I wasn't aware there were adapter specifically designed for 142mm axles
Hope make disc spacers for this exact scenario. I had to use one on one of mine, the brake mount on the frame will be out of spec.
