Bicycle Derailleur Hanger Extension with Screw Compatible with 34T-52T Bicycles

Product Size: The overall length is only 50.8 mm and the center distance is 28.9 mm, offering both high compatibility and stability (a center distance that is too short affects compatibility, and a center distance that is too long affects stability). Compatibility: This product is easily compatible with 40/42/46/50/52T mountain bikes and 34/36/40/42T road bikes. The tail hook surface features a radial groove to increase friction and prevent loosening due to vibrations while riding. The locking screw is made of 7075 aluminum alloy with a higher tightening torque. The structure has been improved for precise adjustment and better responsiveness. The final position is eliminated, the fine adjustment range is widened, and adjustment is more convenient. Easy to Install: It can be directly replaced without adjustment, offering perfect compatibility and high reliability.
