Engineered for Unmatched Performance and Durability

The standout feature of the Demolition Mid-BB is its set of premium, high-quality sealed bearings. These aren´t just any bearings; they are precision-engineered to deliver a buttery-smooth rotation that you can feel from the very first crank. The sealed design acts as a robust shield, protecting the delicate internal mechanisms from the harsh realities of urban cycling—dirt, dust, moisture, and grime. This means you get a longer-lasting, maintenance-free bottom bracket that won´t quit, whether you´re sessioning a dusty spot or riding home through the rain. Stop wasting energy on friction and start transferring all your power directly to your wheel.

Everything You Need for a Dialed Setup

This comprehensive approach ensures a solid, creak-free interface between your cranks and frame, giving you the confidence to push your limits. Available for both the industry-standard 19mm and the beefier 24mm spindle sizes, this kit offers versatile compatibility with a wide range of popular BMX cranks.
