This is Surly's popular, fast rolling Knard tread applied to a 29 plus casing.
What''s 29 plus It''s a tire meant for rims with a bead seat diameter of 622mm (29"), but large volume and ideally shaped when used on a very wide rims. In this case Knard is a 3" tire designed for 50mm rims.
The larger diameter smooths rolling over rough ground, the increased volume adds a bit of suspension and float, the width increases traction, and the sheer size holds speed well. The profile is round and tracks well cornering and off-camber, and will remain effective on rims as narrow as 35mm.
The closely spaced low-block tread grips well on multiple surface types but is most at home on dry rock and packed dirt.
27tpi and 120tpi casings available.
(note: designed for 50mm wide rims. Requires minimum of 35mm wide rim to safely engage bead hook)
