Takes a licking and keeps on ticking.

In order to keep up with the continuing trend of lower and slacker bikes, protecting your chainring is becoming more and more important. So, stay current, double the life of your chainring, and eliminate dropped chains with the OneUp Components Bash Guide. Developed with vital input from EWS World Champions Richie Rude and Jared Graves, this Bash Guide uses reinforced nylon bash guards and a back plate cut from 8mm-thick 7075-T6 aluminum to ensure it can handle the biggest hits. Plus, with a meager weight of just about 100g you may forget it’s even there.

  • Bash guide designed to extend your chainring's life
  • Nylon and aluminum deliver reliable protection at low weight
  • One-tool installation and adjustment keeps hassle to a minimum

Got this because I rode some technical trails and nothing is worst than bashing your crank on a root or rock. I got this and have bashed it instead of my investment. I recommend for sure! I have a Santa Cruz Bronson and it works great. Plus you get spacers to dial in that chain guide which is really cool.

Peace of Mind

Am I going to bash that rock? make it more of a non issue with a bashguard. Easy install, keeps your chain on, and protects your crank.

Given how spendy Eagle chains & chainrings are, I wanted to make sure I protected my investment and got a bash guard out of the gates for my new trail bike. Despite how well most 1x11 or 12 drivetrains hold onto your chain these days, I still opted into getting a bash guard with a top guide.
Install on this guy is soo easy and doesn't even require removing the cranks which is really nice! I was grateful that it came with both a black and green top guide option as well as several different bash plates based on your chainring size, 30, 34, 36.
I only have initial impressions of this product so far, but will chime back in later after I have put it through its paces.

Best investment on my new Yeti. I no longer have any chain drop AND my chain's protected over the rocks that I roll over.

Awesome James, glad to hear and thanks for the review!

Really happy

It is a bit more money but once you get one in your hands you understand the quality of materials you are getting! super easy to install and comes with extra bottom guards to adjust between a 28-36T chainring. I went with the orange additional chain guide and looks really good with my bike. Highly recommend!

Really happy

How did you purchase the additional orange chain guide? thanks

So Nice

  • Familiarity: I've used it several times

This OneUp Guard is really nice, especially because you get the chain guide and the bash guard all in one. I was also expecting it only to come with the green guide but was very surprised to see that it came with an option of green or black. Stoked with this guard thus far, and it's super convenient that it came with the 3 different bash guard sizes to be able to use based on the size of your front chain ring.

Solid product at an affordable price!

I just received my package today with the new OneUp bash guard and guide. Thr build quality of the item is solid. It arrives with 2x chain guides(1-Black, 1-Green), 3x bash plates(28-30t, 32-34t, 36t) along with mounting hardware.

The guide is easy to adjust to fit various size chainrings, with one Allen key.

Hard to beat pricing compared to other products on the market.

I will update my review once I get a few rides in, but initial impressions are A+ and great service with fast shipping from Backcountry is just the icing on the cake!

Solid product at an affordable price!

Sweet Pic, Matt! I really appreciate you throwing up that picture. We have been getting a ton of questions on if this comes with both colored chain guides. Enjoy!!

This affordable and durable bashguard will keep your drivetrain safe. Don't second guess your clearance when climbing over rocky terrain or rolling drops, this bashguard will provide peace of mind.

Super easy to install and fits nearly all chainrings.

Soooooooo Goooood !!!

in my opinion this is the best chain guide system out there I have it on both of my bikes. easy to set up and super durable! plus it fits all sizes of chainrings.
