OneUp has made a chainring protector here, which is really good if you drive in places where there is a chance of hitting a large stone, tree root, or something else. Here, OneUp Underbash will take the hit instead of the chainraing.

It can also be used with an oval chainring and boost system.

The package includes 3 different sizes for use depending on whether a chainring with 28-36 teeth is used.

ATTENTION ISCG05 Underbash can only be used on bikes with 2 ISCG05 holes (Evil, Rocky Mountain eg)
