New S/S chain slipping - why?
Evening.
The chain on my new single speed seems to be slipping. Why do you think this is? More info. below....
I recently bought a 2008 Specialised Tricross / Singlecross bike. I fitted a 16t freewheel (see http://www.pearsoncycles.co.uk/category/499/FREEWHEELS) to replace the 18t one which was a bit low. I got the bike cheap over the net and a mate set it up for me - he loves all that. He put in extra links on the chain - I thought that it then looked too loose and removed them later on. The chain looks fine - no obvious stiff links. Everything 'seems' OK when you look at the bike.
Anyway, under pressure (when really putting the power down) the bike jumps and it sounds & feels very much like the chain is slipping. Not every time though - about one time in 20 or so. This is my first singel speed. I 'm not sure why the chain would slip - is it the chain or freewheel do you think? Any ideas welcomed. Thanks.

Hmmm... You absolutely sure your chain is tensioned enough? 8) Classic symptoms of having a chain thats too loose. If it is tight enough, check your chainline - look down the chain at chain level, going from the sprocket to the chainring, and see if it deflects any (it shouldn't any - hopefully perfectly straight.
Otherwise, im out, unless your sprocket / freewheel gear is worn, but I highly doubt it, as you say it's new...
Otherwise, I'm out :?Boo-yah mofo

Check chain tension first (1/2" deflection mid way along top run). But I doubt that sloppy chain (even if significant variation tightest to slackest - next to NO front/rear combinatios give a precisely consistent tension throughout) would cause this sort of slippage.
Sounds to me like the freewheel. Have you tried it in fixed mode?d.j.
