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 8.3 kg, this is the machine for riders who embrace the unknown and ride straight into it. It pairs our lightweight, aero-optimised frameset with the robust and lightning-fast Force XPLR AXS E1 electronic drivetrain, aerodynamic Vision SC45 carbon wheels, versatile 45mm Schwalbe G-One R tyres, and a comfort-focused Selle Italia Model X saddle.
Groupset
Force XPLR AXS E1 is built for gravel riders who push the pace, combining wireless precision, confident braking, and a lightweight, resilient design. The 13-speed 10-46T cassette and Full Mount rear derailleur deliver smooth, reliable shifts over rough terrain, while refined chain management keeps everything under control when the ride gets rowdy. With simplified setup and rock-solid durability, it’s made for performance beyond the tarmac. The integrated power meter, neatly housed in the DUB spindle, provides stealthy, ultra-accurate data tracking—lighter, longer lasting, and ready to perform in all conditions, so you can train smarter and ride harder, no matter the weather.
Wheelset
The Vision SC45 carbon wheels are engineered for versatility, delivering the perfect balance of speed, efficiency, and control. Featuring a refined 45mm depth and 23mm internal width, this wheelset is optimised for minimal drag, stable handling in crosswinds, and a smooth, responsive ride. Paired with 45 mm Schwalbe G-One R Pro tyres, it strikes the perfect balance of speed, grip, and stability—ideal for riders who push the boundaries across varied and demanding surfaces.
Handlebars
Precision-engineered from high-grade carbon, the Ribble Aero Gravel integrated handlebars combine race-ready stiffness with a streamlined aero profile to reduce drag and enhance efficiency. Flared drops provide added stability and control over rough terrain, while ergonomic shaping ensures all-day comfort. Fully integrated cable routing completes the sleek, cable-free aesthetic.
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.
Suspension Fork Upgrade
When the gravel turns rough and the terrain gets technical, the RockShox Rudy Ultimate fork steps in to smooth out the ride. Available as an upgrade on the Ribble ULTRA-GRIT, this premium suspension fork is purpose-built for gravel racing—offering up to 30mm of tunable travel for improved comfort, control, and confidence. Whether you're carving through gravel or hammering down technical descents, Rudy’s refined damping and lightweight design help you stay fast, focused, and in total command.
Frame Storage
ULTRA-GRIT features a dedicated internal downtube storage compartment, built to keep your essentials such as spares, nutrition, tools accessible mid-ride without saddlebags, external clutter or aerodynamic compromise. The compartment is compatible with the Ribble RIFFT Tool Wrap, a purpose-designed wrap that organises your kit inside the frame for clean, silent, rattle-free storage. Slide it out, sort what you need, slide it back in.

FAQ's
If you're between sizes on the ULTRA-GRIT, we generally recommend choosing the smaller option. It's easier to fine-tune the fit of a smaller frame by raising the seat post or using a longer stem, whereas a larger frame leaves much less room for adjustment.
Build weights are provided for a medium‑sized frame and are intended solely as general guidance. Actual weight will vary based on the selected components and accessories, as well as standard manufacturing tolerances. These figures do not constitute a guarantee or warranty of final product weight, and we may occasionally make minor modifications to specifications without prior notice.

Like all Ribble bikes, the ULTRA-GRIT is covered by a lifetime warranty on frame and forks for the original purchaser. This includes any manufacturing defects in materials or workmanship. The standard manufacturer's warranty applies to all other components including 3rd party suspension forks.
Yes, the ULTRA-GRIT frameset is UCI-approved and has been raced extensively by our pro gravel team, the Outliers.
Yes. The ULTRA-GRIT is available with the optional RockShox Rudy suspension fork. This upgrade improves comfort and control on rougher gravel trails, helping you stay fast and confident when the terrain gets technical.
Yes. The ULTRA-GRIT features enhanced cable integration for a clean, cable-free look. Cables are hidden from view, protected from the elements and shielded from drag.
The ULTRA-GRIT comes equipped with fast, grippy and versatile 45 mm gravel tyres, with frame clearance for tyres up to 50 mm wide. When mudguards are fitted, maximum clearance is reduced to around 45 mm, depending on tyre brand and tread. The fork can also accept a 29 x 2.1" (700 x 53c) mountain bike tyre.
Yes. The ULTRA-GRIT can be fitted with a rear pannier rack using our adaptor kit, providing a practical way to carry up to 15 kg of extra gear (kit sold separately).
Yes. A removable mudguard bridge makes fitting mudguards easy (kit sold separately). We also offer a combined mudguard and rack-mount kit for anyone looking to fit both.
The ULTRA-GRIT is compatible with a 68 mm BSA threaded bottom bracket. BSA threaded bottom brackets offer advantages over press-fit designs, particularly in terms of ease of installation, maintenance and reduced creaking. The threaded design provides a more robust connection, and the standardised threads make it simpler to install and remove.

The ULTRA-GRIT has a maximum recommended system weight of 120 kg, including bike, rider and luggage.
