JW Bicycle Products - Captive Bolt Chain Tensioner
The goal was to create a chain tensioner that did not have a bolt sticking out the back. Bolt stays contained inside the body while the slider moves back and forth. 100% CNC machined from 7075 aluminum. Stainless Steel hardware. Two holes to cover multiple configurations. Bright dip anodize finish. Sold as a pair. MADE IN USA!
** Introducing version 2 **
We listened to rider feedback and made a few changes.
New features include:
- Graduation marks to help with proper wheel alignment.
- Thinner profile on the backside to improve fit with thin chromoly dropouts.
- Flat front surface so you don't have to worry about your hubs washer fitting.
- Reduced CNC cycle times to help lower the cost.
