Hi all,
I have changed the 21t sprocket for a 19t on my Nexus 8 hub. Because I've reduced the circumference, the chain needs tightening. Now, do I take a link out, if possible, or do I just pull the wheel back? At the moment I've tried to slide the wheel back, but that means I can't put the non- turn washer in unless I turn it round 180°.
Is that ok, what is the normal practise?
Thanks for reading this.
Thakery
