Description

We have crafted a World Tour-worthy bike using a carefully curated selection of top-tier components, ready to compete at the highest level. In range-topping Hero specification, the Ultra-Aero SL R features Shimano's professional-grade Dura-Ace Di2 groupset, Zipp 303 aerodynamic carbon wheels, World Tour favourite Pirelli P-Zero Race tyres, and 3D-printed Selle Italia SLR Boost Carbonio Superflow saddle. The integrated aerodynamic carbon cockpit completes the ultimate performance package.

Groupset

The pinnacle of Shimano Road technology and innovation. Dura-Ace 9200 brings new levels of comfort and control to road cycling. With the fastest wireless shifting and even more precise brake modulation, Dura-Ace redefines performance. Wireless 12-speed shifting keeps your bike looking clean while offering the fastest, most precise gear changes available. Speed is the driving force behind Dura-Ace 9200, with every component refined to provide the best on-bike experience, whether you’re sprinting to victory on the Champs-Elysees or crushing your local climb.

Groupset

Wheelset

Zipp 303 Firecrest Carbon is the go-to wheelset for all roads ahead. Lightweight yet strong and resilient, 303 delivers aerodynamic performance without compromise. Paired with a Pirelli P-Zero Race tyre designed to deliver high-performance results. Puncture-resistant without impacting weight and able to maintain grip in wet or dry conditions, this is the tyre of choice for the pro peloton.

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 is aerodynamically optimised to reduce drag in the high-speed airflow disturbed by the rider's leg. A composite shaft absorbs road shocks for vibration-smoothing ride quality, further enhanced by a Selle Italia SLR Boost 3D Kit Carbonio Superflow saddle, featuring a 3D-printed surface designed to maximise comfort and performance and a superflow cut-out for increased flexibility and airflow

Frequently Asked Questions

The T1000/T800 carbon frame weighs 1200 g, and the forks weigh 580 g, for a combined total weight of 1780g (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 T1000 and T800 carbon fibres. However, the SL R features more T1000 fibre within its layup, allowing for a slight weight reduction without compromising its 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 current extension models. However, we have developed a suitable alternative: the Ultra-Aero Extensions. Exclusive to the Ultra-Aero SL R, these carbon extensions bolt into the underside of the handlebars, using the two mounting points typically 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. Combined with the frameset, the Ultra-Aero SL R carbon integrated handlebars cleverly conceal all the cables, preserving the Ultra's super-sleek lines for maximum drag savings.

The frame is aero-optimised around 28 mm tyres and can accommodate 32 mm (manufacturer dependant).

All standard bottle cages and bottles are compatible; this bike 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 x1.5 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 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 simply attach it to the extensions themselves.

Absolutely. However, the aerodynamic profile of the top portion of the handlebar makes finding compatible lights and computers difficult. 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.
