Have an Alfine hub/Bushnell EBB on my Salsa Selma. It's become prone to the chain skipping off at random moments when just riding along, over small bumps etc.
It was set up as it is by my LBS a while back.
Seems to be quite a bit of slack in the chain - would shortening it by a link or two, or rotating the bottom bracket further away from the rear cog, or some combination of the two, cure this? Do you need any particular tools for adjusting these bottom brackets? Do I need a new chain? Or would I be better off getting some kind of chain-keeping device that attaches to the bottom bracket?
Thanks in advance for advice...
