Hi,

I recently replaced the bottom bracket and chainset on my mountain bike. The old bottom bracket had a 122 square taper spindle, while the new one has a 118 octalink spindle.

The problem is, now everything is reassembled, the front derailleur won't move far enough to shift the chain onto the largest gear. I've tried adjusting the screws to give it more movement, and even when I pull the cable by hand rather than using the shifters, it doesn't go far enough. Is my only option getting a new bottom bracket with a shorter spindle?

Thanks,

Ben
