Works like a beaut!!!
*To replace, you do need a crank extractor!This baby slipped in right at home after replacing the old one whose threading was stripped and could no longer hold the pedals. Works like a charm, and hardly had to adjust the derailleurs, perfect for my 21-speed mountain bike! Good price, great look, easy to install, and has held up better than the factory crank arms.

High quality triple crankset works great!
Good quality triple-crankset and easy to install (you need a crank (pedal) removal tool or need to have your bicycle repair shop remove them them for you). I upgraded from a single sprocket so that I could pedal at higher speed with less effort. It works great!

Good replacements
Got a customer that drove he’s without a peddle on the crank . Tried this and it was direct fit . Some tooth on the sprocket was oddly shaped but probably the coating
