Burley Koosah, Nasoke, Spider, Jett Creek, and Sandpoint
Unit clamps below seat using EcoSpeed designed "quarter clamps". These only wrap 1/4 of the way around the frame tube so as not to interfere with cable routing or seat travel. The clamp attaches by
means of a water bottle nut concealed under the clamp. These longwheelbase Burleys are fast, comfortable, quality bikes.
