Ok, a clamp-on drink bottle on your handlebars might not look too neat. But if it is 100° and you are dying, this provides a great survival solution. The clamp mechanism works just like the skewer on a bicycle axle and will securely fit both 7/8" and 1" handlebars. The holder’s angle, height and orientation are fully adjustable and the black resin frame and clamp are ultra-tough. Securely holds most standard water and drink bottles. The best universal holder available. We chased after this one for three years. An Aero RWH exclusive.
