    • This fits a Nautilus U616 Exercise Bike
Color: Left+Right 170mm Diamond Crank
I needed to replace the right crank arm on my Nautilus U616 exercise bike. Nautilus is out of business, so I couldn't get a replacement part from them. These crank arms are the same size and work well as replacements.

Save your money. Cheap China crap. I bought the crank and pedals from bucklos. The crank threads messed up the pedals. Company will send me new cranks but not new pedals.

    • Look great but check the size
Color: Left+Right 152mm Diamond Crank
Look great but wrong size will have to return. I need for an exercise bike that has a 16mm (5/8) square shaft. This is 1/2” (13mm)
