Low-profile protection with the ISCG05 Underbash for riders who want bash defense without chain guides
What Our Gearhead® Experts Are Saying:
“I run this when my frame already has a guide or when I just want simple insurance for my chainring. It’s super light, installs without pulling the crank, and takes real hits without flexing or rattling. It’s one of those parts you forget about until it saves your drivetrain.”
When trail features start creeping closer to your chainring, the OneUp Components ISCG05 Underbash gives us peace of mind without changing how our bike feels. This is the kind of protection we choose when our frame already handles chain retention or when we want the lightest possible setup for aggressive trail and enduro riding. It stays out of the way until it matters, quietly doing its job through rock strikes, ledges, and awkward pedal timing.
