Help - new cog/chain question

616 Views 6 Replies 5 Participants Last post by  Dekes
Help.
I put a new niner cogalicious 19 tooth and a new SRAM PC-68 chain on my SS... I am now getting a lot of chain skip on the steeps when I am really grinding.
The chain ring is definitely showing wear... not sure if that is the problem or if I am running the wrong chain.
Any ideas?
Thanks.

the PC68 is an 8spd chain (3/32in) and single-speed cogs/rings are generally 1/8in. that may be giving you some trouble...

8 speed chains are not incompatable with SS cogs and rings. Indeed, I think it is entirely possible that the 8 speed chain is the most common among single speeders.

Regardless, it could easily be the worn chainring + new chain/new cog combo. Try a new chainring before trying anything else.
i use pc58 chains on my 29. i have used boone chainrings and boone cogs. eno chainrings and boone cogs. boone chainrings and endless cogs. eno chainrings and endless cogs. the 8 speed chains give me no problems.

is it possible your chainline coud be off just a bit? that might be causing the noises.

Thanks all.
I will check the chain line then look at at a new chainring.
Could be that the niner is a ****ed up cog.

Surly for example makes the diametre of their cogs too big, so you need to ride a worn chain on it to make it not skip. Lots of other cogs tend to have this problem as well.
