2021 Bottom Bracket Recall
Marin Mountain Bikes, Inc., in cooperation with the U.S. Consumer Product Safety Commission (CPSC) and Health Canada, is issuing a voluntary recall of the certain model year 2021 bicycles.

Consumers should immediately stop riding your bicycle and contact your Marin dealer for a free bottom bracket replacement, including parts and labor.
Please note that only a limited number of bikes were assembled with a bottom bracket that needs to be replaced, so not all models will be affected. Use the CHECK A SERIAL NUMBER function found here to confirm if the bike was assembled with a bottom bracket that needs to be replaced.
Marin has received reports of nine bottom bracket failures in the US.
Customers outside of North America with these recalled models should contact the Marin distributor or local retailer in their country.
