Ergon offers most models in 2 sizes: Small and Large. The Small and Large label refers to how thick or thin the grip is. There is no difference in the length or ‘wing’ size between the Small and Large. The small grip is best for riders with small hands, those wearing thick padded gloves, and riders riding/racing technical mountain bike terrain. The large grip is best for riders with large hands, commuting, and city riding. We highly recommend visiting an Ergon dealer to get ‘hands on’ with the grip you are considering purchasing. Ultimately, grip size is a personal rider preference.
