Description

Born from extensive R&D, the ULTRA-AERO SL is designed for real-world aerodynamic performance. By optimising airflow between bike and rider, it delivers unmatched efficiency in everyday riding conditions. Rigorously tested against the Endurance SL R, a proven race-winning machine, the ULTRA-AERO SL is faster, lighter, and more refined—unlocking true performance gains. This isn’t just a pro-level aero bike—it’s for anyone chasing speed, efficiency, and the thrill of riding faster for less effort.

Now available as a frameset—designed for you to create your ultimate performance build.

Construction

Every inch of the frame, fork, and seat post is designed for pure speed. The fork seamlessly integrates with the head tube and handlebars, slicing through the wind to minimize drag across all angles. After extensive testing, we found the sweet spot: 68mm x 15mm fork blades—engineered to deliver serious aero gains from 5° and beyond. But here’s where it gets exciting—at 10° of YAW, the fork doesn’t just cut resistance; it creates thrust, turning the wind into an advantage and pushing you forward.

This isn’t just aerodynamics—it’s free speed.

Integration

The Ribble RI-2 carbon integrated handlebar is a proprietary system that conceals every cable while providing optimal fit, adjustability, and seamless integration. This one-piece cockpit exemplifies the perfect marriage of form and function, combining a clean, cable-free aesthetic with advanced aerodynamics to reduce drag by up to 40% compared to a conventional handlebar setup. With a super-stiff carbon monocoque construction and refined ergonomics, the RI-2 system is designed for speed-conscious road riders who prioritise performance and all-day comfort.

Ultra-Aero SL Seatpost

The ULTRA-AERO seat post features a truncated aerofoil profile that's aerodynamically optimised to reduce drag in the high-speed airflow disturbed by the rider's leg. A composite shaft absorbs road shocks for a vibration-smoothing ride.

We offer a lifetime warranty on all Ribble frames and forks for the original purchaser. This covers any manufacturing defects in materials or workmanship, so you can ride with complete confidence. The standard manufacturer's warranty covers all other components.
The ULTRA-AERO SL frameset is approved for use in UCI-sanctioned events. To comply with regulations, the supplied front fork disc brake adaptor must be swapped for the UCI-approved version included with the bike. Failure to make this change may result in disqualification when competing under UCI rules.
Yes. While the aero profile can limit compatibility, the bars are designed to work with standard out-front computer mounts, which fit neatly underneath.
The frame is aerodynamically optimised for 28 mm tyres and can accommodate up to 32 mm, depending on the tyre manufacturer and tread profile.
No. As a speed-focused aero bike, the frame doesn’t feature integrated mudguard mounts.
No. Designed as a pure race bike, the Ultra-Aero SL is not pannier rack compatible.
The Ultra-Aero SL has a proprietary carbon seat post designed to carve the air for additional aero gains.
It accepts a threaded 68mm BSA bottom bracket.
The ULTRA-AERO SL uses a P16 40 x 52 x 7 mm, 45 x 45°, and an ACB40 40 x 51.8 x 8 mm, 45 x 45°, top and bottom, respectively.
The frame uses M12 x 125 mm x 1.5 mm front and M12 x 173 mm x 1.5 mm rear thru-axles (included).
When tightening the axles, do not exceed 10 Nm.
We suggest using: - Lithium Grease for the fixture bolts, bearings, thru-axles and pedal axles - Carbon Fibre Grip for the seat post and carbon fork expander
The Ultra-Aero SL features a braze-on front derailleur fitting.
No, any standard bottle cage will fit. However, the Ribble Aero bottle cage system complements the Ultra's signature downtube, further enhancing the aerodynamic gains.
Yes, the seat post features a universal clamping system for alloy and carbon-railed saddles.
The frame's enhanced cable integration ensures a neat, cable-free appearance, keeping cables hidden, shielded from airflow and the elements.
