- Hollow out style, lightweight and beautiful while ensuring strength. High-quality material, strong, durable and has long life.
- The total length is only 50.8mm, achieving high compatibility and stability (too short center distance affects compatibility; too long center distance affects stability).
- The tail hook fitting surface adopts radial grooves to increase friction and solve the problem of looseness caused by vibration during riding. The locking screw made of 7075 aluminum alloy, and the locking torque is greater.
- 28.9mm center distance greatly enhances compatibility and is easily compatible for mountain 40/42/46/50/52T and for road 34/36/40/42T.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
