Chainwheel trouble...

hey, i dunno exactly what the problem is with my sprocket/chainwheel (whatever you wanna call it) but its like the chain gets tighter as i turn the cranks and then it loosens up again, so i think that the sprocket is like not centered perfectly, but im not sure. so does anybody know how to fix it?

If you have a 3 piece crank you have to make sure that your spacers are put on your sprocket right. There shoukldn't be anything in between your crank arm and your sprocket. If you have a one piece than its probably bent.

On 3 piece cranks theres a spacer that goes in the sprocket(in the little hole in the middle)and that spacer should not be on the side of your sprocket closest to the crank arm. If thats in the right place then it probably just bent.

Profile imperial works great for race and can handle some mild street damage. Most of their sprockets are decnt for all sorts of riding but are mostly designed for race.

no chainwheel is perfectly round, there will always be tighter and looser sections. if its extreme then you may have a problem. chainwheels also wear unevenly, so they should be rotated occasionally if you have alternate holes on it.

I think the Iron Cross is a bit to much for racing specific use. You may want to look at some more racing specific chainwheels that are out there. The RNC Lite Titanium sprocket looks killer. But, the Perv may last you longer as it has 5 positions to allow you to rotate the sprocket and extend life and even out wear.

yeah, that makes sense... but the perv only goes up to 39T on dans, and the rnc lite only goes up to 36T, which i think isnt really racy-like...
