If you're looking for chain bash protection to add to your existing integrated chain guide, then the OneUp ISCG05 Underbash is the perfect solution. A lightweight (68g 32-34T) and incredibly tough bash guard made from 7075 aluminum and glass reinforced thermoplastic parts.

The OneUp ISCG05 doesn't provide chain retention but what it does provide is a level of chain bash protection in the form of an easy to install add-on to your existing chain guide.

The Underbash is compatible with chainrings from 28-36T and includes 3 different sizes of bash plate. Suits frames with 2 ISCG05 tabs only (Evil, Rocky Mountain, etc).

NOTE: The OneUp ISCG05 Underbash should not be used on frames with 3 ISCG05 tabs.


  • Easy installation, no crank removal required.
  • Only a single tool is required for installation and adjustment.
  • Oval and Boost compatible.
  • High-quality Stainless Steel hardware
  • Includes 3 bash plate sizes (28-30T, 32-34T, 36T)
