If you don't need a chain retention device, 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 (Deviate, Evil, Rocky Mountain, etc). Should not be used on frames with 3 ISCG05 tabs. Check with your frame manufacturer to be sure the tabs are strong enough. We run these on our Deviates with no problems.


  • Install without removing your cranks.

  • Boost compatible.
  • Oval compatible
  • Stainless Steel hardware
  • Includes 3 bash plates (28-30T, 32-34T, 36T)
