Hollow stems are cold forged from the highest quality 6061-T6 aluminum available. Featuring an open skeletal design and a dual mid-bolt wedge mounting system, they are lightweight yet maintain a very high level of strength. A 53mm extension stem weighs just 218 grams/7.7 ounces. 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.
These stems come with either a 48- or 53mm extension and a 22.2mm bar bore. To ensure proper clamping force, the stem must be mounted on a fork with at least 45mm of exposed steerer tube. Not compatible with forks that have carbon fiber steerer tubes.

All Box stems are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars we have focused our attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector we have reciprocated with an augmented stem interface with greater surface area. We’ve done this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars we have contributed to increased pedaling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar-to-stem deflection and the consequences can be poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency.
Key differences: In this particular model stem we’ve tailored the Oversized strategy to favor utility and access. The geometry has been altered to allow for easy handlebar removal while at the same time scavenging material from low stress zones. Ideal for those who don’t want to compromise on user experience to gain performance. These stems are engineered for the larger-sized racers.
