The brake adapter serves two purposes:

Adapts 135mm rear disc spacing hubs to work with our MRP Fat Fork 10x135 forks.
Adapts Boost 15x110 brake post mounts inboard by 5mm to allow usage non-boost (15x110) hubs.*

This adapter requires a +20mm rotor sizing from the post mounts it is attached to. So for 160mm post mounts, a 180 or 183mm rotor is required. For 180mm post mounts, a 200 or 203mm rotor is required. 160mm rotors are not compatible with the product.

Includes adapter and two mounting bolts.

*hub and/or endcap adapters must be paired with this part to complete a "non-boost" to "boost" conversion. See our full "Better Boost" kits for all parts needed.

Everything you need

Awesome little kit with everything you need for a factory service. Couldn’t justify what the shop was going to charge so I did it myself. The videos MRP provide make it easier than I could’ve imagined! What I assumed would be a daunting task took only about 90 minutes. My fork significantly exceeded the interval recommendations due to some long bikepacking trips and it literally feels like new now! Thanks MRP. Stoked!

Sad they’re gone!

Glad I could snag one of the last sets of these, bummed that the color options for decals are disappearing! Hope there will be more in the future.

Best chain guide/bash guard yet imo

So far I have 3 OneUp bash guides, an Absolute Black, and now 2 MRP’s. I bought an SLR for my bike and loved it so much I snatched a standard AMg in aluminum for the bike Im building my nephew. By far the best guide/guard Ive used. In fact I wish I knew about these before I bought the other ones. No bs shims or flip up outer guide piece thats either too tight to move or too loose and moves on its own… this one just makes sense and it’s the same price or less than the other ones I’ve seen. I’m definitely sitting with MRP for the foreseeable future.

Awesome Upgrade

I installed the Lift damper in my Fox Performance 38 and it transformed the fork. It’s very smooth and supportive now.

MRP Bash Guard - Ride with wreckless abandon!

Great product, easy installation and bullet proof on the trails. When your tree and rock hopping skills are not up to snuff, this little beauty will bail you out and protect your chainring and frame.
