While fitted on a handlebar, these have a super minimal look to them which makes you wonder if they’re almost too simple. But if you take a peek at some product photos from OneUp, you’ll see that there's quite a bit going on inside of the lock-on sleeve. If you didn’t already know, lock-on grips have a plastic sleeve that runs through the center of the actual rubber which makes it so you can tighten them down to the bar so they don’t slip. This is a tried and trued method used by mostly all grip manufacturers, however there is a drawback to this design. If you come from a BMX background then you’ve probably used slip-on grips for years, and are plenty used to spraying hairspray underneath them so they don’t slide around. Well, slip-on grips are just straight up rubber. So even if a lock-on grip and a slip-on grip have the same outer diameter, the slip-on grip has physically more rubber between your hand and the handlebar. This means a slip-on grip will be a bit more comfortable since there’s more rubber to absorb vibration, making them a bit more gentle on your hands. Do they make me superhuman? Well no, however they just have a noticeably squishier feeling if you grab a pair mounted on handlebars and I like any little bit that helps.
OneUp took this well known knowledge and applied it to their grip’s sleeve. Parts of the sleeve are cut out, leaving more rubber in between your hand and the handlebar. You’ve probably noticed that you usually wear out the top-outer-palm area on your grips as this is where most of your weight pushes into the bar. The majority of the cut-outs of the plastic sleeve on the OneUp grips are towards the outside of the palm area to reduce hand fatigue from the area most affected by handlebar feedback. Also, rather than having lock-on clamps on both ends of the grip, OneUp decided to go with only a single clamp on the inside of the grip so they could fit even more rubber toward the end of the hand. Some people prefer dual lock-on clamp grips as they might feel more comfort knowing they won’t move anywhere, however I don’t feel like these are going anywhere.
