Can you make my F.U.C. with a 100% efficient vertical axle path, please?!
Just buy a specialized........duh
Mine were so efficient they'd follow me to work on mondays just from the stored potential energy in the frame. Not from riding of course......all that leg power went straight into trail motion during the weekend........more the energy stored in the little FSR sticker on the swingarm. If you listen closely you can hear it hum.
