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 the twist and contributed to responsiveness. As the stem is 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.
Slapped it on the kids 16 inch because my kid was complaining about the batteries dieing, I thought the weight being on top might effect something with balance but 100% didn't and she still rips it! Definitely recommended
After speaking with H&S, I took the recommendation of their 4 inch riser bars for my bean sprout kid. It was a straight forward bolt on install. No need for adapters or extensions.
From purchasing to install a faultless service provided. Fast shipping is wonderful.
The ASV levers for the pw50 are a must for smaller riders! Amazing improvement to small rider’s confidence. Thanks again for a great consumers experience.
