Kona Sutra ULTD 2021 - Gravel Bike
The Sutra ULTD is the continuation of a dream to make a drop bar bike as badass as possible. The beloved steel chassis of the Sutra and Sutra LTD plays host to the next iteration of the lineup. The butted Cromoly frame and Project Two Cromoly disc fork hold WTB KOM Light Team i27 TCS 2.0 rims on Maxxis Recon Race EXO TR 29x2.25” tires. That’s right. 2.25” of earth-gripping rubber. When the descents get hairy, you can get low with a Trans-X +RAD dropper post. SRAM Rival 1 flat mount disc brakes and drivetrain keep things moving (and stopping) nicely. This bike is as beautiful as it is beastly, with a gorgeous Prism paint job. Turn heads while you turn over the miles on the brand-new Sutra Unlimited.
Key Features:
- Kona Cromoly
Very few materials offer as much shock absorption, durability and supple-ride characteristics as steel. We’ve never strayed from cycling’s original material and have worked tirelessly to adapt, refine and innovate Kona Cromoly framesets as rider demands continue to evolve.
- Tapered Head Tube
More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it’s needed.
- Tubeless Compatible Rims
Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems.
- 12x142mm Axle
12x142mm, 12x148 and 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142/148/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. For 2017, you’ll see the 12x148 Boost standard in the mix. Boost spacing provides more tire clearance at the chainstay yoke, while the rear wheel is stiffer and more durable relative to a 12x142 thru-axle.
Occasionally, without notice, manufacturers change product design and/or specifications.
