About this item ???????- You have a great handlebar, with the perfect positioning for your brakes and gear shifters, but you're missing some solid bike grips. This is where the Corki Cycles double locking handlebar grips come in. Built for all-mountain bikes, the lock on grips are a pleasure to hold, even on longer rides. Whether you're wearing gloves or riding without, you will enjoy superior comfort, feel, and friction as you hit the trails. ??????? - With mountain bike grips it is inevitable they will eventually need replacing. But before that point, you want to ensure you get some solid riding in first. The Corki Cycles mountain bike grips feature a hexagon grip pattern and are made with non-slip TPR. The TPR is softer than rubber but has a higher tensile strength giving enhanced grip, wear resistance, longevity, and durability. This is not only better for your riding but also for your wallet! ???? ?? - The Corki Cycles bike grips use a double locking grip ring clamp design. The ring clamps are secured using a 3mm Allen key, tightening onto your handlebar. This means that even over challenging terrain the grips will stay secure giving the rider better control. ????? ?????????? - When riding for long periods of time, your hands and forearms can become fatigued. A good pair of grips can help with shock absorption as you ride the trails. Pair that with a superior TPR material and you have better gripping and handlebar control. ???????????? - To install the Corki Cycles lock on MTB grips you will need to have a handlebar with an end diameter of 22mm. Clean the ends of your handlebar before attaching and loosen the grips bolts. Slide the grips onto the end of the handlebar, positioning with good spacing for your shifter and brakes. When you're happy with the bike grip placement securely tighten with a 3mm Allen key.
