OneUp Components V2 Chain Guides Description:

The OneUp Components V2 Chain Guides are lightweight devices that are designed to prevent dropping your chain when aggressively riding or racing your mountain bike or e-MTB. The rugged and stiff 7075 series aluminum alloy backplate comes in several iterations to fit common mounting tabs currently found on mountain bikes. As for the top guide, it is constructed out of glass reinforced thermoplastic that is light, is compatible with both round and oval/elliptical chainrings, is highly wear resistant, and features plenty of room and chainline adjustment to prevent chain rub. In addition, this top guide will flip up and out of the way without needing tools to make it much easier to service or replace the chain. All of the install hardware is made out of black coated stainless steel for excellent corrosion resistance and long life, and it only takes one 4mm hex key to adjust and install these chain guides. Simply align the chain guide to your crank/chainring, tighten the backplate down, set the height of the top guide, flip the guide down, and get ready to shred the trails!


Features:

  • 7075 series aluminum backplate creates a rugged and stiff mounting point, and glass reinforced thermoplastic upper guide reduces potential chain noise and keeps these chain guides light in weight (40g for ISCG05 version, 45g for versions that directly mount to e-Bike motors)

  • Versions available to directly to either the ISCG05 style frame tabs, to directly mount onto a Shimano STEPS/EP8 e-Bike motor, or to mount directly to a Bosch e-Bike motor
