  • Uncoated Crank Arms: The 'uncoated' crankset refers to a crankset without an external layer or coating. It is a novel design that not only enhances the appearance of the crank arm but also improves durability, reduces friction and noise, and protects the crankshaft from scratches and corrosion.
  • Boost Your Performance: Our ultralight mountain bike crankset is designed to help you ride faster and smoother, with a hollow integrated crank axle that reduces weight and increases stiffness.
  • Perfect Fit: With a 104 BCD and narrow-wide teeth chainring, our crankset is optimized for single speed chainrings, ensuring a perfect fit and maximum power transfer.
  • Built to Last: Made from high-quality materials and designed to withstand the toughest conditions, our crankset is built to last and will keep you riding for years to come. Uncoated Crank Arms.
  • Note:These crank and chainring are only suitable for single speed. Can not be used on other speed. If you have any problem before or after purchase, feel free to contact us.

Bought this for my retro commuter build. Just sidewalk and road rides. It works as intended, but I did have to add more grease to the BB bearings.Make sure you get your spacers right, my BB width was a 68mm.Since I was going with a 1 by system, I went with 36 tooth chain ring.Also the the plastic crank cap is plastic and sometimes come loose. So I put loc tire on it. Hasn't came loose since.I've got about 30 miles on these cranks soo far. So their still new.But these cranks are worth the money for city or beach bike.

The look and fit was perfect but the gearing is a bit clunky and hard to get it to hold gear in the highest and lowest.

This product works exactly as intended. The installation was as easy as a normal bottom bracket was. The machining was pretty good. So far it works great with minimal resistance. I would recommend this product.

I like that this perfectly fit my mountain bike and included a bottom bracket as well as preload adjustment tool for the crank bearings. It is the perfect match for a high ratio cassette and I had no problems with chain retention. It is a little heavier than the Shimano that I replaced but feels like it should hold up well. Highly recommended.
