SPEEDLINE PARTS | CNC'D ALLOY BMX CHAIN TENSIONER KIT (15MM)
The Speedline Alloy Chain Tensioners have a 15mm Axle hole and will work with most 15mm 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!
