In some situations people simply need more hand positions. Employing the much proven ergonomic grip body of the GP1 the GP5 introduces a hollow formed composite reinforced ergonomically shaped bar end. Featuring rubberized inserts for positive grip like all of Ergon’s bar ends it can be independently positioned relative to the grip & acts as the clamp preventing accidental rotation. The grip itself is available in two sizes. The GP5 is Ergons largest barend offering. Barend size multi-position 110mm Barend made from lightweight Nylon-Composite (GFK) with rubber inserts Compatible with bar-plug style mirrors. German made rubber compound latex free UV stable. Right & Left specific grips. Available in 2 sizes. NOT compatible with carbon handlebars Size Offered in Small or Large this is the thickness of the grip in h&. The Small & Large are the same length & have the same wing size. The only difference is the thickness of the grip in h&. Riders with smaller hands are best to choose the Small size. Riders with large hands are an ideal fit to the Large size. Ultimately choice of size is a rider personal preference.
