SHIMANO NORTH AMERICA HOLDING, INC. / SHIMANO NORTH AMERICA BICYCLE, INC. One Holland, Irvine, California 92618 U.S.A.

Both SRAM and Shimano offer top-of-the-line components for the best mountain and gravel bikes on the market. If you're looking for the footnotes: SRAM vs. Shimano has been the proverbial “Coke-Pepsi” test in mountain and gravel bike components for decades.

In all other cases please refer back to the retailer that sold you the product or contact SHIMANO at 1-800-423-2420 (US). Please do not return any item directly to SHIMANO unless advised to do so by a SHIMANO agent. If you are asked to send the item to SHIMANO, please select and complete the proper warranty claim form.

You can usually find the bike serial number on the under side of the bottom bracket. The “bottom bracket” is the part of the frame that the pedals go into. So all you have to do is turn your bike upside down and have a look… If it's not there, don't worry!
