If we had to sum up the Hei Hei in one sentence it would be this: The Hei Hei is fast, fun, easy to ride, climbs like a mountain goat, descends like a cheetah, is affordable, has no frills but everything you need with its 120mm of front and 100mm of rear travel, and will ensure that you end every ride with a smile on your face. Run on sentences aside, the Hei Hei has been in our lineup for decades because it&&';;s one of the best bikes we&&';;ve ever made. It blurs the line between XC and trail bike and has proved that great ideas evolve into bikes with staying power.SPECIFICATIONS Frame Material Kona Race Light 6061 Aluminum Butted 100mm Travel Sizes S, M, L, XL Rear Shock RockShox Monarch RL Solo Air Fork RockShox SID 35 DebonAir 120mm Tapered 110mm Spacing Crankarms SRAM NX Eagle DUB Chainrings 34t B/B SRAM DUB PF92 Pedals n/a Chain SRAM NX Eagle Cassette SRAM PG1230 11-50t 12spd Chainguide n/a F/D n/a R/D SRAM NX Eagle Shifters SRAM NX Eagle Brake Calipers SRAM Level T Front Brake Rotor SRAM Centerline 180mm Rear Brake Rotor SRAM Centerline 160mm Brake Levers SRAM Level T Headset FSA No.57B Handlebar Kona XC/BC 35 Stem Kona XC/BC 35 Seatpost TranzX Dropper +RAD Internal 31.6mm Seat Clamp Kona Clamp Grips Kona Key Grip Saddle WTB Volt Front Hub Formula 110x15mm Rear Hub Formula 148x12mm Spokes Stainless Black Rims WTB ST i27 TCS 2.0 Front Tire Maxxis Forekaster EXO TR DUAL 29x2.35" Rear Tire Maxxis Forekaster EXO TR DUAL 29x2.35" Paint Color Matte Faux Raw w/ Metallic Mint & Metallic Silver Decals All specifications are subject to change without notice.
