The OneUp Components ISCG05 Underbash is the perfect addition for those not seeking chain retention or for bikes with an integrated chain guide. This product offers excellent bash protection. The Underbash comes with three different sizes of bash plates, ensuring compatibility with chainrings from 28-36T.
It is specifically designed for frames with 2 ISCG05 tabs only, such as Evil and Rocky Mountain. If your bike has three ISCG05 tabs, it is recommended to 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.
The Underbash is easy to install without removing your crank and requires only a single tool for installation and adjustment. It is boost compatible and oval compatible. The package includes stainless steel hardware and three bash plates (28-30T, 32-34T, 36T).
Specifications include a weight of 68g for the 32-34T capacity, a chainline of 2.5mm adjustment, and a mount of ISCG05 2-Bolt ONLY. The Underbash is available in black and is made from 7075 aluminum and glass-reinforced thermoplastic.
