The GP5 combines the GP1 grip with a 5 finger multi-position bar end for maximum hand positions and increased leverage. Perfect for commuting, touring or for those who like a longer bar end. The bar end angle can be adjusted independently from the angle of the grip for the perfect personal fit and the bar end doubles as a clamp to lock the grip in place and prevent movement while riding. The Ergon GP4 is made from 100% German, TÜV-certified rubber compounds of the purest quality.Sizing Information:In order to help you maintain perfect control over your bike, your hands should not completely envelop the grip, which is why Ergon offers many grips in two size diameters Small and Large.The difference refers to the grip width (hand size), meaning a larger hand will have a more positive fit on a thicker grip, while a smaller hand is better fit to a smaller grip. For hand/glove sizes 6.5 to 8.5" we recommend Small, for 8.5 to 10.5" Large usually is better. To measure your hand/glove size you need to measure around the largest part of the hand over the knuckle while making a fist, excluding the thumb.
