Product Description The GP2, GP3, GP4 and GP5 Gripshift bar ends (as of model 2015) by Ergon, without bar ends. Compatibility:Ergon GP2Ergon GP3Ergon GP4Ergon GP5Size Guide:As hand sizes considerably vary depending on the person, Ergon's grips from the GP and GS series are standardly available in two sizes, small and large. The size difference refers to the grip circumference. This means that a larger hand will fit better on a thicker grip. Likewise, a small hand has a better grab on a thinner grip. These differences have a direct impact on the handling of the bike as a whole.
