OneUp ISCG05 Bashguard

Never drop a chain again. The OneUp Components Bash Guide ISCG05 V2 combines upper chain retention with lower bash protection in one lightweight, bomber package — developed with EWS World Champions and trusted on the world's most demanding enduro courses.

Installs with a single 4mm hex key without removing your cranks, and the tool-less upper guide flips open to get the chain back on if needed. Boost and oval chainring compatible.

Not compatible with e-bikes, Gen 5/6 Trek Slash alloy, Fuel EX carbon/alloy, Ibis Ripmo/Ripmo AF, or high pivot frames.
