Speedline Parts | CNC'd Alloy BMX Chain Tensioner Kit 3/8" (10mm)

The Speedline Alloy Chain Tensioners have a 3/8" axle hole and will work with most 3/8" (10mm) hub axles.

Its single-bolt design keeps chain tension uniform and straightforward.

We also moved to a single-bolt design to cut down on weight. It's only a few grams, but those saving add up!

Our chain tensioners come in a pack of two, available in various colors!
