Product Description

By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, we reduced the weight and size and eliminated a serious hazard to the rider’s knees.

The BOX Hollow BMX Stems come with a 48- or 53-millimeter extension and a 5-degree rise or drop.

To ensure proper clamping force, the stem must be mounted on a fork with at least 40 millimeters of exposed steerer tube.

Available in Anodized Red, Blue, Gold and Black with laser-etched graphics and six hollow chromoly Allen bolts. Meets or exceeds ENBMX Category 1 standards. Fits 22.2 Ø handlebars. Not compatible with carbon fiber steerer tube forks.

  • 48mm-213 grams/7.5 ounces
  • 53mm-218 grams/7.7 ounces

BMX Parts Guide

What are BMX parts?

BMX parts are any components for upgrading or replacing your BMX parts.

Who needs BMX parts?

Any BMXer looking for a performance upgrade, or just to bling up their bike from the selection of brightly coloured bits on offer.

What are the choices?

Pretty much anything you can think of – improve comfort with saddles, pedals or a pair of grips. Change the drivetrain with colourful chains, sprockets and cranks. Add stunt pegs or replace bottom brackets and handlebars – the sky’s the limit.

What should I buy with them?

Mix or match, the choice is yours. Pick a colour theme for your bike and go for coordinating components, or break the mould with multicolour kit.

Anything else?

It’s really important to check compatibility when it comes to BMX parts, so make sure whatever you choose will work with your bike.

See our BMX bike guide for more.
