This is a similar Knard tread we previously introduced on a 29 x 3˝ casing, made up of low, closely spaced knobs, an effective tread for going fast over varied terrain. We chose 41mm because it’s meaty enough to conform to the ground surface, absorb irregularities and provide a decent sized contact patch.
Bead Seat Diameter: 700c x 41mm
(622mm Bead Seat Diameter, 41mm casing width) (Note: 23–30mm recommended rim size.)
