Description
Steel Chain Tugs – Pair
Keep your chain perfectly tensioned with this pair of steel chain tensioners, designed to fit bikes with 10mm (3/8″) rear axles.
Compatibility & Application
- Suitable for 3/8″ (10mm) axles, commonly found on BMX, single speed, and some track bikes.
- Designed to slide onto the axle, allowing for smooth adjustment and secure chain tensioning.
Important Fitment Note 
Please be aware:
The hole size on these chain tensioners is slightly larger than 10mm to allow the part to easily slide onto the axle. This is intentional — if the hole was exactly 10mm, it would need to be screwed onto the axle, which would make installation impossible.
The 10mm size refers to the axle they are designed to fit (3/8″ – approximately 9.5mm to 10mm), not the exact internal diameter of the hole itself.
