Ryan,

To add on to Jerry Moos' comments, another area you could look at would be the condition of the FW cog that is skipping. Sometimes it is hard to notice, but the FW cog can wear in the shape of shark's tooth and this wear can cause new chain to skip. If you are satisfied that this is the case and the FW has this appearance, grind off the rearward elongation at the top of the cog. Less than a mm of grinding should do it. I had that happen to me and that was the fix.

The only trouble I'vd ever had with a new chain, presuming the the chainring and freewheel are not excessively worn, is with a tight link. On a modern chain, check that the master link is properly installed and that the chain bends properly there. If that's OK, work your way arround the chain bending the chain between each pair of links enough to insure that the links move freely. If you find a tight link, loosen it with a chain tool. It usually takes only a tiny movement of the pin to loosen up a tight link.

Regards,

Jerry Moos Big Spring, TX

About 3 months ago, I installed a new chain (SRAM PC58) on my 1 year off-topic Ciocc Mockba 80 with on-topic SR crank and chainrings (53/43) and Regina 13/21 6-sp FW. Since then I have been averaging about 2 skips per 12 miles a day, always under moderate-to-heavy load. If anything, it's getting worse. The equipment was previously mounted on a Paramount with no problems.

I just measured the old chain and it was not stretched. The teeth on the FW are very strong. I've measured them and am (nearly) satisfied that the FW isn't the problem, which leaves the new chain. The tension is good. I've tried to identify a stiff link, but just don't see it. When I tried flipping the chain it was so bad that I had to flip it back five minutes later.

Is there a "breaking in the chain" ritual you can suggest? Is it possible the chain is just bad? Am I overlooking something else?

I'm fairly new to this and am hardly a mechanic, so please forgive me if I'm asking naïve questions. I read the archives heavily before writing. My local bike shops haven't been able to help.
