Honjo 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.

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, so this fender does not wrap quite as far around an ultra-wide 26″ tire as it does with narrower 650B tires. It still provides better spray protection than any other fender we’ve tried.

Aluminum fenders keep you drier and your bike cleaner. The uninterrupted inside profile and rolled edges keep water inside, rather than let it drip onto your feet and drivetrain. Generous coverage prevents spray at the source. Stiff U-shaped stays keep the fender securely mounted, so it does not rattle or resonate on rough roads. The smooth finish is simple and beautiful. Set includes front and rear fenders plus mounting hardware.

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

Made in Japan.
