Our Alloy Chainguard is an easy, affordable way to keep your pants and calf clean from bike grease when using an internal gear hub or single speed/fixed gear.
What you get in the package: one guard with the bottom bracket drive side mount pre-assembled and hardware to mount to the drive side chainstay.
First, untension chain.
Remove crank arms. If you have a VO Crankset, you can pull the arms without using a special puller; you only need an 8mm wrench. Start removing the drive side bottom bracket. The non drive side can stay in. Clean shell and threads.
Put bottom bracket body through chainguard and re-install into bottom bracket shell.
Assemble chainstay clamp and re-install wheel.
The crankarm may touch the guard. Don't be afraid to push the guard to clear the arm. Different cranksets have different tolerances/q-factors. Note, the bottom bracket will be shifted out to the drive side a couple millimeters, but not enough to really notice any difference.
Confirm everything is tight, ride around to make sure frame flex doesn't change tolerances.
Enjoy! Btw, this thing is shiny.
