Check to see if the cog has a bent tooth, also check chainline and if the cog (i assume the fixed one) is facing the right way (not flipped or backwards.) Are your hub cones lose? Axle nuts tight? HTH

I'm no pro but a few ideas / double-checks for starters:

* Is the chainline still straight? Perhaps the fixed cog isn't spaced the same as the freewheel, and the chain is going in or out too far on the fixed side.
* Is the fixed cog smaller, possibly causing a slack chain?
* Is the back wheel pointed straight? One time on a SS freewheel I didn't check the back wheel enough after adjusting for chain slack and it was pointed a little to the left--I wasn't losing my chain every 10 feet, but it did have a tendency to pop off on bumps. Note that I don't mean out of true, I mean that I literally just needed to pull the axle a little farther back on the right side.

Hope it helps!

This could help. It does seem that the chain does have more slack. How can I fixe this. Do i need to buy a new chain. I am new to have a fixed gear.

If you bought it at a bike shop bring it in and have them check. Most shops offer warranties and will fix a bike that they sold to you for free.

It just sounds like your chain needs to be tightened. You should definitely check out the link above. It will tell you all you need to know.

couldn't it just be chain tension and axel tightness? fixed gear puts alot more strain on the wheel, to the point where u have to be really sure its on there right and straight or else it'll just make life so much worse for you.
