MPM-TECH EXCHANGE CAGE SHIMANO XTR-XT 12 SPEED
Delivery date: 1-2 giorni
WHY USE EXCHANGE? The Exchange gearbox cage is CNC machined from solid ALU 7075 alloy. It is equipped with 12T-18T pulleys with oversized, high precision and smoothness bearings. Delrin hoods that completely cover the bearing, preventing water and mud from penetrating. The 18T lower pulley improves the transmission speed and reduces the stresses of the chain in the technician. The inner cage is equipped with anti-tear threaded bushes, which prevent the cage from opening, increasing its safety. This version is only compatible with Shimano Xtr / Xt 12 speed and the maximum supported toothing is 52T. How to replace your cage: 1) put the clutch off, unscrew the cage stop by unloading the spring (as on sram even if shimano has no button lock) 2) Unscrew the 3 screws that hold the clutch cover in place 3) once the cover has been removed, there is a hole with a 4mm hexagonal seat in front of it. By holding the cage still and unscrewing the bushing, the cage is self-extracting from the other side.
