Fitbikeco BF Stem

This stem is designed specifically for 1 1/8" threadless steer tubes, which is the standard size for most modern BMX bikes. It is not compatible with tapered or threaded steer tube systems found on many mountain or road bikes.

The reach affects your cockpit space and steering responsiveness. A 48mm reach offers a slightly quicker, more twitchy feel, while the 51mm reach provides a bit more stability and extra room in the cockpit for taller riders.

You will need a 6mm Allen key to tighten the bolts. Ensure you tighten the bolts in an 'X' pattern to distribute pressure evenly across the handlebar.

Yes, the BF stem is CNC-machined from high-grade aluminum, balancing a lightweight profile with the structural integrity needed for trail use. It is built to handle the demands of serious riding while maintaining a clean, classic aesthetic.

The 33mm rise is considered a medium height, which helps elevate your handlebars for a more upright and comfortable riding position. It is an excellent choice if you are looking to relieve pressure on your back or wrists during longer sessions.
