I have a mountain bike - a Stumpjumper hardtail frame with a Shimano drivetrain - where I'm getting a good amount of chainslap. Before I start fiddling with stuff, I'd like to understand the problem better.
This is a new-to-me bike that's only recently been built from a mix of old and new parts.
(I've put up more pictures of the bike here, but these are the two that most clearly show the drivetrain.)
I believe I have two options here:
- Increase the tension on the chain (somehow), or
- Pull links out of the chain until all is well.
What are the advantages and disadvantages of both? Or are there other strategies I'm missing? Or is my time better served by simply wrapping the chainstay and living with the problem?
(While this isn't strictly relevant, I'd be remiss if I didn't point out that the front derailer also has issues - I can't get enough cable tension to get the chain to shift into the big ring up front.)
