OneUp Components ISCG05 Underbash - Black

The OneUp Components ISCG05 Underbash provides lightweight, reliable protection for your chainring against rocks, roots and trail obstacles. Designed for bikes that don't require upper chain retention or already have an integrated chain guide, it adds essential lower chainring protection without unnecessary bulk.

Featuring a durable 7075-T6 aluminium backplate and reinforced thermoplastic bash guard, the Underbash includes three interchangeable bash plates to accommodate chainrings from 28T to 36T. Its adjustable design allows for 2.5mm of chainline adjustment and can be installed without removing the crank.

With a simple single-tool installation, Boost and oval chainring compatibility, and stainless steel hardware, it's a practical addition for riders looking to protect their drivetrain on demanding trails.
