Grips

thicker ones absorb vibrations and suit larger hands, thinner ones give better feel and fit smaller palms. An ergonomic shape with a flared section under the palm relieves your wrists on long rides, but some find it gets in the way in technical terrain. Lock-on versions do not twist even when wet and you can change them with a single Allen key; slip-on ones are cheaper, harder to remove and start spinning over time. As soon as a grip starts slipping with sweat, it is time for a new one.
