GANOPPER Gancio per deragliatore posteriore per bicicletta in lega da 2 pezzi per bici da strada TREK8500 TREK8000 TREK6700 TREK6500 TREK6300 TREK6000 TREK4900 TREK4500
The Rear Derailleur Hanger - No 10 fits my Trek 4300 perfectly, replacing one that had been bent quite badly causing bad shifting. If you look at the hanger on your bike or google the model and year it is likely that you will find one of these to fit - they are standard designs but do differ between ages and models. The quality is great and shifting is now back to normal, plus I now have a spare it it happens again!
