Chain slipping after installing new chain.

mark8191

Changed my worn out 11 speed chain for a new KCM one today.
I've noticed when I back pedal on the biggest cog and small chainring it slips up two gears. It doesn't do this in any other gear or chainring and don't think I've noticed it before so wondering if I've done something wrong or this is normal?

I lined the two chains up before installing and attached two narrow links with a quick link.

Advice much appreciated.

It's possible that it's always happened - could be a hanger alignment "issue".

How does it actually ride?
How worn was the chain?
Have you changed the cassette as well?

Suspect wear somewhere assuming your gears worked ok prior to chain being replaced. I usually go by the following 3 chains replaced then replace cassette and possibly top ring on my full sus depending on wear. See YouTube for how to check setup etc.

Shifts fine
The chain was worn to .50.
Cassette has about 2000 miles on

It's probably okay then, to be honest. I'm assuming it doesn't skip under load... I would think 0.5% is in time to avoid that. Especially on a relatively new chain.

It might just be the thick grease the chains are packed in- making the chain slightly stiffer. Nothing to worry about.
