Box Components Three V-Brake

Yes, the Box Three V-Brake Kit is a complete solution that includes both the brake caliper and the corresponding brake lever. You will only need to provide your own brake cable and housing to complete the installation.

The size refers to the length of the brake arms. The 85mm version is typically used for smaller BMX frames or junior setups, while the 108mm version is the standard size for most adult and pro-level BMX race frames. Check your current brake arm length or your frame's geometry specifications to ensure the correct fit.

This kit is specifically engineered for BMX racing. While it uses a standard V-brake design, the lever pull ratio and arm length are optimized for the geometry and braking demands of BMX tracks, rather than the varied terrain of mountain biking.

Like any high-performance V-brake, these require minimal upkeep. Periodically check the brake pad alignment and wear, and ensure the cable tension is adjusted so the lever engagement feels crisp and responsive.

The kit includes a matched lever designed to work perfectly with the caliper's pull ratio. While you could technically mix and match, using the included lever ensures the most consistent modulation and stopping power intended by the manufacturer.
