MrDiyFan · 2016-08-29 11:48:27

Hi.The chain on my 8 speed shimano is hitting underneath Is the chain too long or is there any adjustment to the jockey wheels that can be made? There's a small bit of slack when in the 2 big cogs but not a massive amount,thanks.

Chain is to long.

There are adjustments you can make but generally it's the chain.

Plenty of vids on youtube.

when you say slack, do you mean the chain is hanging/bowed on the run from the lower jockey wheel to the bottom of the chainring?
