So why did RevGrips make Hand Guards?  Our local trails have been tremendously overgrown (at least the places we like to ride) and throughout our rides, we'd get struck with branches, bushes, even a cactus or two.  It started to impact our rides negatively, and that needed to change.
We looked around to purchase something that would work well and compliment our ride's look.  We ALL get inspired when our bikes look good right?  There are only a couple options for MTB handguards anyways, and nothing really looked all that cool, so we decided to make our own. 
We took the same approach to Hand Guards as we do to every other product we manufacture.  We set out to make something we're proud of, something worthy of the RevGrips badge.  Hand Guards aren't known to be the most attractive component around… we wanted to change that.  
Our Hand Guards are manufactured in our facility in CA.  The Shield is made of high-strength, transparent gray Polycarbonate.  The Mount is 6061-T6 Billet Aluminum, anodized Dark Gray to match our other components.  Not only do our Hand Guards look pretty cool, they also work great and install in minutes.  
Check out our Instructions (link here) for more installation information.
Replacement Shields are available as well (       ).
IMPORTANT NOTES FOR HAND GUARD SERVICE/INSTALLATION
Clean Polycarbonate Shield with Soap and Water ONLY.
DO NOT use LOCTITE or any other thread locker for the Shield Screws.  If it contacts the Shield, it can/will cause a chemical reaction, and the Polycarbonate will crack.
