Features a collar-less design to eliminate local stiffening and improve clamp force distribution - Squeezy acts like a thin metal band that perfectly snuggles around the circumference of your seat tube and smoothly secures your seatpost in place - The compact design and titanium bolt placed as close to the seat tube as possible allow even distribution of loads. Dopper posts in particular can benefit greatly from evenly distributed loads - Three "slip-stops" prevent Squeezy from sliding down and take the place of a traditional collar - AL-7075-T6; 8g (35mm), 9g (38mm)
