Box Components Hex Lab Oversized 28.6 X 1" Front Load Stem

All Box One front load stems are engineered and crafted using Oversized Technology. As we follow the load paths down the handlebars and have focused 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. By moving material from low-stress areas. This has greatly minimised twist and contributed to responsiveness. As the stem is mated with the handlebars we have contributed to increased pedalling 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.

Box Components 22.2 X 1-1/8" Centre Clamp Stem

Box Two Centre clamp Hollow stems are cold forged from the highest quality 6061-T6 aluminium 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. This stem can be installed either side up to give a 5-degree rise or drop. Note: Not compatible with forks that have carbon fibre steerer tubes
