Replaced a 3 speed crank on my mountain bike with this.....shaved about a pound of weight and the crank arms are a little wider so the footing is better on the pedals...worth every penny.

Installed this new Crankset on my Mongoose Fat Tire bike. It seemed to work okay on the 1st day, with the exception of the chain making a slight rattle. 2nd day chain noise getting worse and finally chain would not stay on Crank Sprocket. Flipped my bike over to inspect Crankset and found 2 teeth out of alignment, causing the chain to come off at the same place on the sprocket every time. Obviously a defected item. Chose to return item within my 30 day grace period. Would like a full refund or a new Crankset.

I originally bought Meroca cranks off eBay. The pedal holes were not drilled straight, basically junk. Got these on Amazon in one day to replace those. Better quality and went on smoothly. Idk about long term strength and longevity, but highly recommend as of now. Pedals threaded smooth and straight. Square taper went on nicely too. Also like the black sprocket bolts!First test ride, the bike was rode for 18 miles, no issues.
