The Kink Ideal bar ends give you some unique options.
The standard size 31mm bar ends give you full sized, traditional bar end and grip coverage.
The smaller 22mm size gives you just the bar end, which means your grip will actually cover up the bar end. This is great for catching bar spins or grabbing the end of your bars, since the bar ends will be fully covered by the soft rubber of your grips.
Both sizes use a simple and lightweight three piece wedge design, that install with a common 6mm allen key.
