Gunnar Hyper XF Disc

Gunnar Hyper XF Disc
Please select options


Color: Midnight Purple

Size: 52cm

A gravel bike takes many forms, from lightweight racers to long-haul expedition machines. Many manufacturers build multi-surface bicycles, but the bikes from Gunnar are a special breed. Handcrafted from steel in Waterford, Wisconsin.

The frame of the Hyper XF Disc is built with True Temper's OX Platinum chro-moly steel. This steel alloy offers a supple ride, while boasting light weight and outstanding durability. Up front, a 44mm head tube adds to the Hyper XF's handling precision, especially in technical terrain. Out back, the Hyper XF features flat-mount disc brake mounts that reduce overall bike weight and reduce caliper twisting for better brake performance. A 12mm rear thru-axle ensures excellent hub alignment and higher torsional rigidity. Rack mounts, fender mounts and bottle cage bosses add versatility to the Hyper XF. The fork is an all-carbon Whisky Parts Co. unit, keeping overall weight low while soaking up fatiguing vibration over rough terrain. The fork's flat-mount brake caliper installation and 12mm thru-axle dropouts keep the Hyper XF current.

Gravel bikes need to be durable, performing under grueling conditions and dirty terrain. The Hyper XF's components reflect this approach as well, with SRAM's Rival 1 drivetrain doing power delivery duties. The alloy Rival 1 crankset is a single-ring setup, with a 42T X-Sync chainring. A Rival 1 shifter operates a Rival 1 rear derailleur, featuring a Roller Bearing Clutch for improved chain retention. A SRAM 11-42T cassette offers a wide gearing range for challenging terrain and heavy touring loads. Rolling stock consists of Shimano's WH-RS770 alloy/carbon fiber wheels, bringing very light weight and solid durability to the Hyper XF. Straight-pull spokes and direct-mount brake rotors keep the hubs tidy and light. SRAM Rival 1 hydraulic disc brakes help keep speed reigned in, rain or shine (or mud).

Zipp produces the alloy Service Course seatpost, alloy Service Course SL stem, and SL-70 drop handlebar. Fabric provides the saddle, finishing off this outstanding gravel challenger.
