OneUp Components ISCG 05 Underbash

ISCG05 Underbash

£49.99

If you're not looking for chain retention or your bike has an integrated chain guide, you can still add some bash protection with the OneUp ISCG05 Underbash.

The Underbash includes 3 different sizes of bash plate for compatibility with chainrings from 28-36T. Designed for frames with 2 ISCG05 tabs only (Evil, Rocky Mountain, etc). If your bike has three ISCG05 tabs, check with the frame manufacturer to ensure the lower tabs are strong enough for a bash application. Failure to do so could result in frame damage.
