Triple F Rear Dropouts

Triple F is short for “Form Follows Function” and that is the philosophy behind the design of the Triple F’s. After building thousands of frames using countless types of dropouts I was left wanting a dropout designed with function first and foremost in mind and that drove me to design the Triple F. The result is a dropout that is simple, small, light and strong. All excess material has been removed leaving a clean organic shape. I of course use the Triple F’s on my own bikes and I also offer them to other builders who can show proof of insurance. If you are a builder wanting to use Kirk Triple F’s on your bikes please contact me for details and pricing.
