Tech Tuesday - MRP XCG Guard Installation

Apr 26, 2011
by Mike Levy  
MRP's XCG guard is designed to protect your chain rings from damage - especially important considering the replacement price of some of the current 2x10 rings. Watch MRP's own Noah Sears guide you through the installation.

Some pointers before you begin...

• The XCG guard is just that, a guard designed to protect your chain rings and crank arms - especially important considering the replacement price of some of the current 2x10 chain rings. Check out MRP's other options if you're looking for a guide to keep your chain in place.
• MRP's XCG guard is available in three versions depending on whether you are looking to protect a big 44 tooth ring, or the smaller 40 and 36 tooth rings used on some double chain ring setups. There are also models to fit ISCG or ISCG-O5 chain guide tabs, as well as a bottom bracket mount version.
• When mounting to ISCG tabs, always use the longest mounting bolts possible. More thread engagement means more strength.
• A touch of blue Loc-Tite on the guard mounting bolts will keep them from rattling loose down the road.
• Use the supplied spacers to move the XCG guard close enough to the ring that it will provide protection, but not so close that the crank's chain ring bolts touch the XCG's back plate.

What you'll need:: 4mm and 8mm hex wrenches, some installs will also require a crank extractor or bottom bracket cup tool as well.

 Been on 3 rides now with the XCG40 and I am pumped! Having run a 2x10 set up that didn't allow for an outer bash all last season I was looking at swapping out my cranks to something else that allowed for this. Now after installing and riding the XCG40, my confidence has gone up because I'm less concerned with replacement ring costs and can slide over the odd log as opposed to sticking into it. It's a simple thing, but there are enough of us out there now that can benefit from this.

 I have the 44t one, and it has suited me well for big ring and 2x9 w/ a 36t big ring's pretty sicky! Would purchase another one for sure without a doubt.

 Really? That's your comment? You are probably the same clown who made dumb comments on the basic flat repair tech tuesday as well. There are people out there who appreciate this sort of thing, even if you don't.
