Review on Sturdy Silver SUNLITE Unicycle Cotterless Steel Crank Arm Set for Smooth Riding by Jerome Brooks

Bought these to replace the regular cranks on an exercise bike after replacing a double knee - haven't had enough range of motion to do a full rotation with the regular cranks yet. In the first order there was only one handle, the left one. The replacement order came with two rights so I kept a few and returned the extra right as the first order. You can buy in advance to make sure the order is correct. Quite heavy, steel, galvanized, but quite suitable for an exercise bike. Secure fit, no play, the sewn hole fits the square crankshaft well. If I had to do it again (knee replacement) I would buy 5" and 6" kits, that was probably 4 weeks or so in advance. I might even swing a 6 inch set
