The outer diameter is thicker than normal grips, so it is very suitable for people with large hands. The sleeve lining is made of high-strength hard plastic, which is solid and stable. It can be cleaned. It is fine to add some washing powder or other cleaning liquid with a brush. After washing, it can be dried and it can become very new. Note: When installing and tightening the hexagon socket screws, it is recommended not to use too much force, because the locking screw is 4mm, and the locking ring is aluminum alloy. If the force is too strong, it will become a screw or a sliding tooth of the locking ring. Pay attention to the locking when tightening the screw. The gap of the ring tightly, if the sleeve can be turned after it is tightly closed, do not tighten it again, and the tightening will cause a slippery tooth. Please communicate with the seller in time if there is a problem with the installation (the installation tool is not included in the box) Package Included: 1 pair of gloves
