I need a pair of Crank Arm Shorteners? I have a crazy disease (Scleroderma) that causes the Skin and other Soft tissues to harden. I was in a wheelchair and 2 yrs later I walk 2-3 miles a day. I just recently bought a Bike(next step in my recovery),I can barely ride it because of the length of the pedal stroke. I went online and found the shorteners,I don't have much money and they cost about 100$. I live on SSI and was wondering if anyone out there had a used pair or a deal on some new ones. I'm so excited to ride the new bike,I road Bikes my whole life and haven't been able to ride for over 5 yrs! Thanks for your help!
