Description

The ULTRA-GRIT is Ribble’s fastest gravel bike—developed and proven by our pro gravel team, the Ribble Outliers, in the chaos of the world’s toughest off-road races, from Unbound to The Traka to The Dirty Reiver. Weighing just 8.9 kg, it's built for riders who thrive on the unknown. This durable build pairs a lightweight, advanced carbon frameset with SRAM’s Rival XPLR AXS wireless groupset. DT Swiss alloy wheels, versatile 45mm Schwalbe G-One R tyres, and a Selle Italia Novus Boost saddle complete this race-worthy package.

Groupset

Rival XPLR AXS is built for riders who go deep into the wild and push hard every mile. Its tough, lightweight design delivers precise 13-speed wireless shifting across a 10-46T range—so you're always in the right gear, whether grinding up loose climbs or sprinting to the line. The Full Mount rear derailleur shrugs off abuse, while refined braking keeps you in control on technical descents. With a spindle-based power meter seamlessly integrated into the redesigned alloy crankset, you get the reliable data you need to ride smarter, train harder, and explore further—without adding bulk or complexity.

Groupset

Wheelset

Boasting a wide rim profile and robust construction, the DT Swiss G 1800 Spline alloy wheelset delivers confident control and comfort across rough and unpredictable gravel terrain. Paired with 45 mm Schwalbe G-One R Performance tyres, it strikes the perfect balance of speed, grip, and stability—ideal for riders who push the boundaries across varied and demanding surfaces.

Handlebars

Built to take on the rough stuff, the Ribble Gravel Riser handlebars bring comfort, control, and versatility to every ride. A 20 mm rise gives you more hand positions and extra space for running a bar bag—perfect for long hauls and bikepacking missions. The flared drops widen your stance for rock-solid stability when bombing descents or picking through technical terrain. Wrapped in plush bar tape and paired with a semi-integrated RS-2 alloy stem, this setup is ready to tackle whatever the trail throws your way.

SADDLE

Stay stable and comfortable over rough terrain—our integrated seat post clamp, combined with a proprietary D-shaped carbon seat post and the Selle Novus Boost Evo saddle, delivers excellent rear-end compliance and effectively reduces trail chatter for all-day comfort.
