MPM-TECH Dust shifters 12-13t Shimano Grx long cage

Manufacturer: MPM-TECH
Delivery date: 3-5 giorni
These pulleys are entirely machined from solid, made of Ergal and assembled with bearings of the highest quality; 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.
