The Shifty V2 allows you to replace the standard derailleur pulley on your SRAM rear derailleur with a high-quality, precision-machined aluminum pulley with a sealed stainless steel ball bearing. This guarantees reliable and smooth shifting even in adverse, muddy, or dusty conditions. The Shifty V2 is compatible with SRAM 1x11 and 1x12 rear derailleurs as well as the current SRAM Eagle 70 and 90 Transmission models. The appropriate bearing inserts for both variants are included, ensuring easy and precise installation. Ensure that your drivetrain always works perfectly and reliably – in all weather conditions.
