BOX Components are famous for their oversized technologies that have lead to the introduction of tapered steerers, 20mm front axles as standards for BMX racing. Their latest offering is the B52 bottom bracket. They are the size of the USA bottom bracket from the 80’s but they are threaded instead of press fit. Why? Well you can read that below. The only frames that have a bottom bracket shell made to take them right now is the Race Inc. Could we be witnessing the introduction of a new standard BB size for BMX racing? Time will tell.

Manufacturer’s Description

We couldn’t ignore the undeniable truth about bottom brackets. Traditional BBs lack the space necessary for the pedal stiffness you deserve. That’s why we designed the B52 Bottom Bracket to bring Oversized Technology into your bike frame, breaking the mold in the bike builder’s world. With a 52mm wide BB shell, your bike gains wider chainstays, enhancing efficiency during cornering and acceleration. Your power delivery becomes more efficient, and feedback becomes more responsive. In summary, you’ll need less energy to achieve the same elapsed time. String together as many Oversized components as you can to banish flex from your setup.

Key differences: By advancing the boundaries of the BB shell to 52mm, it  allows us to encase the bearings for improved durability. With enhanced support, bearings handle high torque with less complaints, reducing shaft wobble due to minimal internal clearance. This leads to improved power delivery, enhanced concentricity, longer service life, reduced vibration, and limited axial motion.
