Description

The Ultra-Aero SL R results from doing something that has never been done before. It guarantees gains never seen on a road bike and is aerodynamically optimised to make your fastest rides even faster. In Sport specification, it's paired with Shimano's 105 Di2 electronic groupset, lightweight and dynamic Ksyrium 30 alloy wheels, 28 mm Pirelli P-Zero Race tyres, and a unisex Selle Italia Model X Superflow saddle. The ground-breaking Ultra integrated aerodynamic carbon cockpit completes this race-ready package.

Groupset

Shimano 105 Di2 is the culmination of years of research and development. By combining technologies and functions inherited from Dura-Ace and Ultegra, 105 Di2 will transform your road cycling experience. With a shared Di2 platform, sophisticated ergonomics, 105-optimised gear combinations and the exceptional stopping power of hydraulic disc brakes, Shimano 105 Di2 marks a new era of performance, making accurate, lightning-fast, and reliable electronic gear shifting more accessible to all.

Groupset

Wheelset

Ksyrium 30 Disc is the perfect entry point into high-level race performance. This tubeless-compatible wheelset's dynamic ride quality helps you roll faster and smoother while retaining a lightweight feel for climbing and accelerating. Paired with Pirelli P Zero road tyres; which balance performance with durability, for both reliability and comfort. The carcass features excellent puncture resistance, whilst coming in at an impressively low weight.

Handlebars

Engineered exclusively for our fastest-ever aero bike, the Ultra-Aero bars redefine aerodynamic integration with a patent-pending, next-generation design. At the heart of this innovation is a groundbreaking wake-generating concept that disrupts airflow, creating a controlled wake for the rider’s legs to sit within while strategically manipulating vortexes to enhance overall aerodynamics. The aggressive, drag-defying anatomic wing top section reinforces the bar’s aero dominance, cutting through the air with precision. But speed isn’t the only priority—comfort is integral to the design. The flat-top section offers a secure and relaxed hand position for climbing, while the ergonomically optimized drops naturally conform to the rider’s palm. With a textured finish that eliminates the need for bar tape, every detail is fine-tuned for performance and control.

Saddle

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 quality further enhanced by a Selle Italia Model X saddle. Designed with sustainability in mind but without compromising performance, Model X features a glue-less assembly; with gel padding and a superflow cut-out for all-day ride comfort.

Frequently Asked Questions

The T1000/T800 carbon frame weighs 1200 g, and the forks weigh 580 g, for a combined total weight of 1780 g (size medium). The approximate build weights are Sport—8.25 kg, Enthusiast—8.20 kg, and Hero—7.8 kg.

Similarly to the SL, the Ultra-Aero SL R's construction features a bespoke blend of Toray T1000 and T800 carbon fibres. However, the SL R features more T1000 fibre within its layup, allowing for a slight weight reduction without compromising strength, stiffness, or structural integrity.

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.

Not in the traditional sense. The bars' aggressive profile prevents compatibility with all current extension models. However, we have developed a suitable alternative: the Ultra Aero Extensions. Exclusive to the Ultra SL R, these carbon extensions bolt into the underside of the handlebars, using the two mounting points normally reserved for an out-front computer mount. Anyone wanting to mount a cycle or GPS computer can mount it to the extensions themselves.

The Ultra-Aero SL R has a 68 mm BSA threaded bottom bracket shell, allowing for ease of maintenance and enhanced reliability.

Cycling's governing body has approved our SL R frameset for competition in UCI-sanctioned events. However, the disc brake adaptor for the front forks must be swapped out for the alternative version supplied with the bike. Failure to follow these guidelines when competing in events carried out under UCI regulations may result in disqualification.

Yes, the Ultra-Aero SL R carbon integrated handlebars, in combination with the frameset, enable all the cables to be entirely hidden. This preserves the ultra-sleek lines for maximum drag savings.

The frame is aero-optimised for 28 mm tyres and can accommodate up to 32 mm (manufacturer-dependent).

All standard bottle cages and bottles are compatible; the Ultra-Aero SL R is optimised to actually be faster with a bottle and cage fitted than without.

Two. One is situated on the down tube and one on the seat tube.

The frame requires M12 x 125 mm x 1.5 and M12 x 173 mm x 1.5 front and rear thru-axles.

Due to the Ultra-Aero SL R being a speed-centric aero bike, there aren't any integrated mudguard mounts.

We recommend a maximum system weight of 120 kg (bike, rider & luggage).

Yes, you can. The carbon extensions bolt onto the underside of the handlebars, utilising the two mounting points that are typically reserved for an out-front computer mount. Anyone wishing to attach a cycle or GPS computer can do so to the extensions themselves.

Absolutely. However, the aerodynamic profile of the top portion of the handlebar makes it difficult to find compatible lights and computers. To overcome this, we've designed the handlebars to accept any compatible out-front computer, which bolts into the underside of the handlebars.

We do not supply pedals with our bikes due to the various systems people use. However, when configuring your bike, you can select from a range of our best-selling pedals.
