In other words if the tight spot occurs when your right pedal is at the top as mine does then the sprocket is obviously at its furthest forward point when this happens so shimming the opposite side to the part the chain is on will help bring it back to.

Bmx chain has tight spot. The shim should be even all the way round the spacer but if this isnt possible then you need to put it at the back at the point when you normally get the tight spot. Unfortunately yes all chains get tight spots. Either way this quick video has some really solid advice especially for those of you new to working on a BMX bike.

Turn the bike upside down turn the cranks until the chain is sagging in its loosest spot. Ive had tight spots in a chain before and its often down to corrosion or dirt inside the link generally the only proper fix is a new chain and new sprockets too if theyre worn.

Several things can cause this like ubugless says. The shim should be even all the way round the spacer but if this isnt possible then you need to put it at the back at the point when you normally get the tight spot. But I end up usually having to give it a bit more cuz its hard to dial that in exactly and its just easier to give the gears some room to breathe and not be perfectly concentric or round.

It seems that the chain is getting tighter when a certain area gets to the frontrear sprocket. Actually they are not totally identical because no two things ever are. When you put the chain back on.

Or having a loose chain tearing through your frame. For now I got it to a medium ground where it ends up being a little looser at one end and a little tighter at another. The MacNeil sprocket is more than likely thicker than your stock sprocket which could offset the chain slightly.

The sprocket might be off-center. This can be very subtle but you can see the difference between the sprocket or the chainring being off-center depending on how many times per turn the chain reaches its tight spot since the sprocket has a much smaller diameter.

If you have chain tensioners they take a lot of the work out of holding the wheel in place while you tighten because your axle is being held tightly in place with those screws.

Sometimes the front sprocket hole will get oblonged on the spindle. In other words if the tight spot occurs when your right pedal is at the top as mine does then the sprocket is obviously at its furthest forward point when this happens so shimming the opposite side to the part the chain is on will help bring it back to. Never seen a chain that runs with equal slack the full trip around so some tight and loose spots seem to be the way it is.

You can often tweak this a little by slightly loosening the chainring bolts and using the tiny amount of play between the chainring and spider to get a slightly better fit. Loosen all the chainring bolts and pull the sprocket to tighten the loose spot in the chain and at the same time retighten chainring bolts. Play around with the spacers in your BB if you have to get new ones just get washers from your local hardware storr.

The chain itself can be unevenly worn out or be uneven from factory.
