Rocker Dropouts
Slider Dropouts |
Seven offers two adjustable drop out options for cyclists who want to run a single speed, or internally geared hub, while using disc brakes.
What are adjustable drop outs?In order to add tension to the chain, a requirement for single speeds, adjustable drop outs allow the rear wheel to be slid or pivoted once fastened. By moving the wheel away from the crank set, chain tension is increased. What is the difference between the Slider and the Rocker style drop outs?Sliding drop outs slide back and forth and have the disc caliper mounted in the traditional, behind the seat stay, location. People who want a simple solution to a disc brake single speed often choose the slider drop outs. Rocker drop outs pivot and require a low mount disc set up. This set up allows for easier installation of a rack and fender because the disc mount location won’t interfere. In addition, the rocker drop out allows for a 12 x 142 mm thru axle should you want additional stiffness in the rear wheel. How much do adjustable drop outs cost?$350 on titanium or ti/carbon frames, $150 on steel. |
