Nano 40 is built for speed. A nearly uninterrupted centerline provides swift efficiency on hardpack terrain while staggered outer knobs allow you to stay on the gas while hammering up chunky climbs or hanging on through loose gravel corners. The high-volume 40mm casing allows for lower tire pressures and a smoother ride while still reducing drag and rolling resistance. This makes for an all-out gravel destroyer that still appeases those clamoring for a truly big cyclocross tire. Everybody’s irrefutable favorite, ‘nough said.FEATURES:Minimal rolling resistance due to raised, consistent centerline tread.Long, staggered knobs provide steadfast traction without cutting down on speed.TCS Light/Fast Rolling versions of the Nano 40 tire provide ultimate tubeless reliability for gravel or cyclocross racing.Race and Comp level tires are designed to provide optimal performance at a competitive weight, but must be used with inner tubes.
