OneUp ISCG05-V2 Chain Guide

The OneUp Chain Guide ISCG05-V2 is built for riders who want to stay focused on the trail — not on dropped chains. Engineered to completely eliminate chain loss, this lightweight and no-fuss chain guide is one of the most rider-friendly solutions on the market. At just 40 g, it's crafted from durable 7075 aluminum with a glass reinforced thermoplastic upper guide, striking the ideal balance between strength and weight savings. It handles chainrings from 26 to 38T, features a 7.5 mm chainline adjustment range, and is fully compatible with Boost and oval chainring setups. The tool-less upper guide flip makes trailside adjustments effortless, and the entire installation requires nothing more than a 4 mm hex key — no crank removal needed. Whether you're charging through technical singletrack or sending it on steep descents, the ISCG05-V2 keeps your drivetrain protected and your momentum uninterrupted.
