The Hyper XF Disc is an evolution of the original multi-surface Gunnar CrossHairs. The geometry is still nimble and confidence-inspiring, and the weight is still very low for an adventure-oriented steel-framed machine. This Hyper XF Disc is Ultegra-equipped, making it a real performer over paved and unpaved surfaces.

The Hyper XF Disc starts with a handmade True Temper Platinum OX cro-moly steel frame that provides a smooth and supple ride quality. An oversized 44mm head tube anchors the fork's tapered steerer, enhancing cornering precision. Flat-mount disc brake installation and replaceable thru-axle dropouts simplify brake rotor alignment and improve torsional strength. Rear rack mounts add versatility to the Hyper XF Disc, while a slightly upright fit allows a wider range of rider positions. Cable routing is external on this example. The Whisky Parts Co. carbon fiber fork is also a 12mm thru-axle unit with flat-mount brake installation. The all-carbon construction is effective at soaking up fatiguing vibration while adding torsional strength. There's room for tires up to 40mm.

Our in-stock Hyper XF Disc is equipped with Shimano's high-performance 11-speed Ultegra components. Power delivery is through an alloy 50/34T Ultegra compact crankset, while an 11-32T Shimano cassette boasts a wide gearing range. The latest version of Ultegra derailleurs require less hand strength to operate, and feature shorter shifter throws. The rear derailleur is a Shadow-style unit with a more tucked-in profile that enhances shifting performance as well as being slightly more aero. The front derailleur's cage is tapered to allow wider tires as well.

The wheelset of the Hyper XF Disc is a great example of "road plus" design. Widerness Trail Bikes provide the tubeless-ready KOM Tough alloy rims, bringing easy acceleration and wide rim profile. WTB also supplies the wide-flange alloy thru-axle hubs. Brake rotors are installed with 6-bolt mounts. Hydraulic disc brakes have come of age, and Shimano's Ultegra units are clear leaders in the field. The "R-8070" Ultegra flat-mount calipers resist twisting under hard braking, promoting more even pad wear. The brake pads themselves are finned for faster heat dissipation during repeated hard braking, especially when loaded down.

Whisky Parts Co. produces the Hyper XF's carbon fiber seatpost, reducing total weight and improving road feel over buzzy washboard surfaces. There's also a Whisky Parts Co. No. 7 alloy stem up front. A Bontrager Arvada Comp saddle provides a comfortable perch for long miles over unpleasant surfaces. Salsa manufactures the 24-degree flared Cowchipper drop handlebar, allowing a more upright posture and better leverage on technical terrain.

Gunnar Bicycles offers a wide range of frame designs. options and colors to help make your next bicycle uniquely your own. Please call for details.
