Unanswered Question

Is the ISCG05 Bash the bash guard and guide combined? The image and description are misleading but the price is consistent with the guode/bash combo.

Don't get dropped

  • Familiarity: I've used it several times

This is a set and forget component. As a real OneUp fan it was a no brainer to add this to my bike. Dropped chains are mostly a thing of the past but it's nice to have a small, light and simple assurance it definitely won't happen especially if you are drawn to the rougher terrain and high-speed chatter.

Prevents dropped chains!

  • Familiarity: I've put it through the wringer

An easy to install chainguide that prolongs the life of your drivetrain and virtually eliminates chain drop. It comes with black, and green guide, as well as a bunch of different shims to get the proper spacing.
