The padding is narrow and dense. This helps with improves feel and steering. Two different rubber durometers are used, softer against the hand and firmer underneath. The increased surface area of the wings that support the outsides of your palms adds comfort.
As with most of grips, there’s an aluminum alloy clamp on the inside of the grip. It’s easy to lock into place and small enough not to interfere with controls. The outside still has room to easily install bar ends, if that’s your wont.
