Rene Herse Smooth Fenders 650B for 38-44 mm tires (H80 650B Std)


This elegant fender is a perfect fit for one of our most popular tires, the Rene Herse Babyshoe Pass 650B x 42 mm.

Aluminum fenders keep you drier and your bike cleaner. The uninterrupted inside profile and rolled edges prevent water from coming out on the sides of the fenders. Rene Herse fenders are made to our specifications by Honjo in Japan, with longer blades for better coverage to keep your feet and drivetrain drier and cleaner. Special Rene Herse mounting hardware (included) ensures a rattle-free, secure attachment. Detailed, illustrated instructions guide you through the installation process.

Also available with tubular fender stays that save 35 g without a loss in strength. 

Pro Tip: This fender also works well for 26″ tires 48-55 mm wide, like the Rene Herse Rat Trap Pass, if mounted 25 mm above the tires. The width of 62 mm provides clearance for the chain with road cranks in all gears without the need to indent the fender.
