Gunnar Gunnar Hyper-X 7020

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-X 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-X's handling precision, especially in technical terrain. A long wheelbase improves stability on rough surfaces. Out back, the Hyper-X 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-X. The fork is an all-carbon Whisky Parts Co. unit, keeping overall weight low while soaking up fatiguing vibration over rough terrain. Multiple bottle mounts on the fork blades make preparing for multi-day gravel tours that much easier. The fork's flat-mount brake caliper installation and 12mm thru-axle dropouts keep the Hyper-X current.

Our in-stock Hyper-X is equipped with Shimano's excellent 11-speed 105 components. Power delivery is through an alloy 50/34T 105 compact crankset, while an 11-32T Shimano cassette boasts a wide gearing range. The latest version of Shimano's 105 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 installation of wider tires as well. Bontrager supplies the tubeless-ready alloy Paradigm Comp wheels, bringing durability and light weight to the Hyper-X. The rims feature a 21mm interior width, allowing a given tire to spread out for a better "footprint". Meaty 700x43c tubeless-ready Panaracer GravelKing SK tires boast plenty of grip on crumbling surfaces. Shimano hydraulic 105 disc brakes provide excellent stopping power in all conditions, rain or shine. The Hyper-X's cockpit is also from Bontrager, including the Verse Comp road saddle, seatpost, alloy Elite road handlebar and accessory-ready Elite Blendr stem.

Gunnar bicycles can be built to your custom specifications, including frame fit, geometry, frame details, accessory mounts, and even color. Please call for details. Keep in mind that delays are still ongoing in the bike industry, and that turnaround times for custom bikes are still subject to change.
