TPR lock-on handlebar grips with aluminum alloy clamp rings on each end. The lock-on design prevents rotation and sliding — most relevant on rough terrain where push-on grips tend to shift. 22.2mm inner diameter - fits the standard bar diameter on most MTB, road, and folding bikes. Not compatible with 31.8mm or oversize bar ends. 133mm length - suits most adult hand sizes and leaves room for controls on standard-width bars. Verify available bar space if you run wide brake levers or multiple controls. TPR grip body - thermoplastic rubber with texture for hand contact without a tight grip. Holds up to UV and sweat over time. Aluminum alloy lock rings - one ring each end, tightened with a hex key. No adhesive needed; removal is straightforward for component swaps. ~105g per grip - pair weight is light enough not to affect the build noticeably. What's in the box:2x lock-on handlebar grips (pair)
