Priority Gemini Smart Shift Belt Drive Gravel Bike

The Priority Gemini Smart.Shift is a high-performance gravel and adventure bike that combines the durability of a Pinion gearbox and Gates Carbon Drive belt with fast electronic shifting and a comfortable drop-bar riding position. Built for gravel, bikepacking, touring, and mixed-terrain adventures, the Gemini delivers an exceptionally wide gear range without a traditional chain, cassette, or derailleur.

At the heart of the Gemini is the Pinion C1.12i Smart.Shift 12-speed gearbox, providing a massive 600% gear rangefor everything from steep, fully loaded climbs to fast gravel roads. Electronic Smart.Shift technology changes gears in as little as 0.2 seconds, with shift controls integrated into the TRP Hywire brake levers. The system provides up to 20,000 shifts per charge and has a 6,000-mile gearbox service interval.

The Pinion gearbox is paired with a Gates CDX Carbon Drive belt, creating an exceptionally clean and low-maintenance drivetrain. With no derailleur hanging off the back of the bike and no chain to lubricate, the Gemini is particularly well suited for dirty gravel rides, long-distance touring, and bikepacking trips where durability and reliability matter.

The Gemini is available with either a butted 6061-T6 aluminum or 3Al-2.5V titanium frame, paired with a carbon fork. Adventure-ready rack, fender, and frame mounts make it easy to carry gear, while internal routing provides compatibility with a dropper post. Its 12-degree flared drop bars provide multiple hand positions for long days in the saddle while adding leverage and control when the terrain gets rough.

WTB KOM Team i23 tubeless-ready wheels and 700 x 40mm WTB Vulpine tires balance speed and traction across pavement, hard-packed gravel, and loose surfaces. TRP Hywire hydraulic disc brakes provide powerful, controlled braking in changing conditions.
