Promax - C-2 Chain Tensioner (BMX)
C-2 Chain Tensioners feature a minimalist design to keep the weight as low as possible. Extruded and CNC-machined from 6061-T6 aluminum for optimal strength and low weight.
When used properly, they will protect your frame dropouts and help hold your rear wheel in place.
Available in anodized red, blue, gold and black with black hardware. C-2 Tensioners are intended to be used by smaller and lightweight riders.
