MPM-TECH Dust pulleys 12-12t Shimano ultegra 8000 / dura ace 9150 / grx gabbia media / shimano mtb 11 speed

Manufacturer: MPM-TECH
Delivery date: 1-2 giorni
The dust pulleys, in this version 12t-12t for Shimano ultegra 8000 / dura ace 9150 / grx medium cage / shimano mtb 11 speed are entirely machined from solid, made of Ergal and assembled with very high quality bearings; the special design makes them extremely rigid at a torsional level and a particular processing makes the known chain "straddle" that sometimes happens with traditional or low quality pulleys almost impossible.
