The KH27.5 is a top quality unicycle designed for all-mountain riding. The slightly larger wheel size reduces rolling resistance and feels agile on difficult trails. The high volume, Duro Crux 3.25” tire is well supported by the 55 mm wide rim and feels stable and forgiving. The aggressive tread pattern grips securely in mud but, combined with a rounded tire profile, still corners smoothly on pavement, slickrock and compact dirt.

Recommended for all-around muni riders wanting a unicycle that excels for both climbing and the descent in a wide range of conditions.

Highlights include

  • One-piece forged, 7005 alloy frame crown and neck for high strength without bulk
  • Rounded fork blades and forged crown provide “plus size” tire clearance in a slim profile frame
  • KH Boundary Hub and Cranks with Q-Axle micro spline for high strength and stiffness
  • Disc brake with large (203 mm) rotor for increased braking control
  • Fusion One saddle for bike-like saddle performance with a one-piece forged Pivotal seatpost for high strength and easy adjustability
  • 55 mm wide rim for high tire stability
  • 27.5”x3.25” Duro Crux tire (81 mm measured width) provides massive grip, shock absorbency and smooth cornering, without feeling clumsy or hard to control.
  • Compatible with KH/Schlumpf geared hub (not included)

General Minimum leg inseam length (ground to crotch, wearing shoes) for KH27.5: 73 cm
Note: minimum leg length may be reduced by 25+ mm by selecting different components, such as a slimmer saddle model and non-adjustable seatpost (to reduce saddle height), and shorter cranks (to raise the lowest point of the crank rotation). Advanced users may also shorten the frame seatpost tube by up to 25 mm. Note that frame modifications void the KH warranty.
