MRP Better Boost Kit

How to convert to Boost spacing with our Better Boost Kits
The change from “standard” to “Boost” spacing left many people in the lurch when wanting to upgrade a crucial component on the bike: the fork. Without an adapter, a new front wheel or new hub plus wheel rebuild is required to upgrade to a Boost fork. Between the two products, you’d be dropping some serious cash.

We created the Better Boost Adapter Kit to eliminate that costly inconvenience. These kits allow you to keep your current wheel and upgrade to your fork of choice. There are other conversion kits on the market, but they typically include just one hub end cap, which requires you to re-dish your wheel so it is properly centered in your fork. That process is a pain. And that’s what makes our kits Better.

6-Bolt Better Boost
The six-bolt Better Boost Adapter Kit is simple. It consists of two precisely machined end caps, a brake rotor spacer, and the necessary bolts. Installation is easy, taking just minutes.

Centerlock Better Boost
We also offer a Centerlock Better Boost Adapter Kit. Because it’s not possible to space a centerlock rotor mount on a hub outboard, we instead provide a brake caliper adapter that moves your brake caliper inboard 5mm. With this kit installed, you essentially have Boost axle spacing, but standard rotor spacing. The brake caliper adapter does require you increase your rotor size one size up from the post-mount standard you are mounting it on. Some forks use 160mm post-mounts, thus with the adapter you’d use a 180mm rotor. Other forks, including our Ribbon forks, use 180mm post-mounts, so you would need to use a 203mm rotor. The Centerlock Better Boost Adapter Kit includes two end caps, brake caliper adapter, and adapter mounting bolts.
