Three Brake Kit

What Our Gearhead® Experts Are Saying:

"This kit gives you everything you need to upgrade a BMX brake setup without overcomplicating things. I used the 85mm version for tighter clearances and was impressed by the pad feel and lever ergonomics. Installation was simple and it fits great even on compact frames."

When it comes to dependable stopping power that doesn't weigh you down, the Box Three Brake Kit gets it done with clean looks and smooth control. Whether you're building up a race bike or upgrading a street rig, this complete kit includes cold-forged 6061-T6 alloy arms and a reversible lever with reach adjust for left- or right-hand mounting. The finned dual-compound brake pads stay cool under pressure and offer excellent modulation and grip, even in mixed conditions.

We love the choice between 85mm or 108mm arms to suit different tire and rim profiles. Thoughtful touches like a barrel adjuster, Phillips head tension screws, and cable routing make setup easier than ever. It's everything we need to stop hard—without overcomplicating the ride.
