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 8.0 kg, this range-topping build is made for riders who thrive on the unknown. It pairs a lightweight, aerodynamic frameset with SRAM’s flagship Red XPLR AXS gravel groupset, featuring a built-in power meter for pro-level training and race insight. Zipp 303 XPLR carbon wheels, versatile 45mm Schwalbe G-One R tyres, a 3D-printed Selle Italia Novus Boost saddle, and a carbon integrated cockpit complete this ultimate performance package.

Groupset

RED XPLR AXS is built for gravel racers and serious riders chasing every advantage. It delivers ultra-lightweight performance, crisp wireless shifting, and one-finger braking—so you can attack climbs, rail descents, and stay in control at full speed. The 13-speed 10-46T cassette offers tight steps to keep you in the power zone, while the Full Mount derailleur adds rock-solid reliability with no hanger or adjustment screws to worry about. The spider-based power meter with dual-sided measurement tracks every watt with pro-level accuracy, giving you the data to push harder, train smarter, and hit your goals—no matter how big the ride.

Groupset

Wheelset

The Zipp 303 XPLR SW wheelset is purpose-built for gravel, delivering exceptional speed, control and efficiency across rough terrain. Its ultra-wide rim is designed specifically for modern gravel tyres, increasing air volume so you can run lower pressures for improved grip, reduced vibration and better climbing traction without sacrificing stability. Built around Zipp’s Total System Efficiency approach, it combines aerodynamic performance with a lightweight feel that keeps you fast and comfortable over long distances. Paired with 45 mm Schwalbe G-One R Pro tyres, the setup strikes an ideal balance of speed, grip and stability, giving you the confidence to push further across varied and demanding surfaces.

Wheelset

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.

Handlebars

Saddle

A narrow D-shaped carbon seat post introduces flex where it counts, helping to take the edge off the roughest surfaces for a smoother ride, leaving you feeling fresher for longer. Paired with a Selle Italia Novus Boost 3D Kit Carbonio Superflow saddle, featuring a 3D-printed surface designed to maximise comfort and performance and a Superflow cutout for increased flexibility and airflow.

Saddle

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.

Suspension Fork Upgrade

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.

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.

  • Apex XPLR AXS build: 9.0 kg (carbon forks) / 9.7 kg (RockShox Rudy Ultimate)
  • Rival XPLR AXS build: 8.9 kg (carbon forks) / 9.6 kg (RockShox Rudy Ultimate)
  • Force XPLR AXS build: 8.3 kg (carbon forks) / 9.0 kg (RockShox Rudy Ultimate)

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 features a 1.5" integrated headset and R457B 52 x 42 x 7 mm 45° x 45° headset bearings top and bottom.

The ULTRA-GRIT features a D-shaped carbon seatpost with an integrated wedge clamp, designed for compatibility with carbon-railed saddles. XS–SM frames are equipped with a 280 mm post, while M–XL frames come with a 330 mm post.

The ULTRA-GRIT features two bottle cage mounts with one on the seat tube and one on the downtube. Both are positioned to work seamlessly with Ribble Aero Bottle Cages for optimal aerodynamic performance.

The ULTRA-GRIT includes extra luggage mounts on the top tube and underneath the downtube.

Thru Axles:

Yes. While the ULTRA-GRIT comes with a 1x drivetrain, it can also accommodate a braze-on front derailleur using an optional derailleur hanger (sold separately) and 2x gravel chainsets (31T/48T max).

The ULTRA-GRIT uses a universal derailleur hanger (UDH), standardising hanger design across bikes. That means no more hunting for a frame-specific hanger with just one simple, universal solution.

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

No. Pedals aren’t included as riders use different systems. You can, however, choose from a range of best-selling pedals when configuring your bike.
