De Venta 21 Speed Gear Set Kit for Bicycles Fit for All* Cycles, Cycle Accessories Combo of 12 Parts, Cycle Gear Kit Set, Make Your Bicycle Multi Speed Bike

I recently purchased this and I couldn't be happier with my purchase! It provided me with 21 speed options, allowing me to upgrade my gearless cycle into a 21-speed bicycle effortlessly. The installation process was a breeze, and it worked seamlessly with my bike's size and type. The kit includes all the necessary components, from the crank and chainwheel set to the rear and front derailleurs. The durably built accessories and 7-speed freewheel added a fantastic touch to my biking experience. Highly recommended!

I am returining the product as left side threa lock is missing in the sealed crank and It is not possible to assemble rest of the parts without a proper sealed crank.Rest of the parts are ok but due to this missing/incompelete sealed crank i am returning this product.
