VO Alloy Chainguard Installation Made Easy

by Igor

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.

Do they come with the logo etched on now?

You'll have to re-tighten the none drive side cup after this procedure. The chainguardbracket spaces the axles towards the driveside.

Love the shiny look with the not-shiny bike. Like my bike.
Anyone tried to run these with a 1x8?

Can you do this with a French threaded BB, or would it be a bad idea to make it even harder to tighten?

I once saw a bicycle, I think it was a Civia, that had a chain guard AND a derailleur drivetrain. The chain guard was simply wide enough to accommodate the motion of the chain. I have never been able to find any information about it online. If you make such a product, you've got a customer here.

Please note that the stated size is near the maximum chainring that will fit.

I really like mine. I have a 39 chainring with the 38 chainguard. But A 42 chainring will not fit the 38 chainguard.

I run a 1x8 with no problem, 42 up front, 11-32 in back, although note that I asked a pro to install it to be on the safe side. Occasionally, when I go over a bump, I get metallic chain slap as it flexes upwards, no big deal. The one accommodation I had to make was at the rear attachment: the derailleur would bounce up and hit the rear bolt, scratching up the derailleur and making noise. I added a wide rubber washer, the kind VO offers for other uses, to the bolt, and that took care of it. The guard is great in all kinds of weather. My crankset has a bash guard in the place of an outer ring, and the bash guard sits nicely within the 42 chain guard with no rubbing, making for a pretty good enclosure and no chance for coming off the front ring. Plus it looks like an old Hot Wheel.

Pictured is our 44T Fluted Single MK2 crankset and 44T chainguard. Works perfectly.

That's great @crmodgeon, but if running 1x8 you might as well use internal gearing. The guard that I saw worked with a double.

Dave M., my frame has vertical dropouts, but even if it didn't, to me that's like saying I might as well spend $300 more than I have for a heavier, more unwieldy component that creates as many problems as it solves. The range of a standard cassette is adequate for my needs, and for the price of an IGH I could practically buy a new wheel set. If I wanted to go whole-hog, I suppose I could pair an IGH with a full-enclosure chain case, but the chain guard in question fills a nice niche. And above all, I love the dancing chain.
