eMagTech Bicycle Derailleur Hanger Extension with Screws Suitable for 34T-52T Bike

Product size: The total length is only 50.8 mm, and the center distance is 28.9 mm, which has both high compatibility and stability (too short a center distance affects compatibility, and too long a center distance affects stability). Compatibility: This product is easily compatible with 40/42/46/50/52T mountain bikes and 34/36/40/42T road bikes. The surface of the tail hook adopts a radial groove design to increase friction and solve the problem of loosening caused by vibration during riding. The locking screw is made of 7075 aluminum alloy with a larger locking torque. The structure is upgraded to achieve precise adjustment and improve the speed response speed. The end position is cancelled, the fine-tuning range is increased, and the adjustment is more convenient. Easy to install: It can be directly replaced without adjustment, with perfect compatibility and high reliability.
