Produktdetails

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.

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