Description

Designed to offer you the ultimate performance advantage in every situation, the Pro edition of the Ultra SL is fully capable of propelling you to the top step of the podium, smashing your PBs, or claiming KOMs. This competition-ready package is fully kitted out with high-end components, including the peerless shifting precision of Shimano’s latest Ultegra Di2 2x12 wireless electronic transmission, lightweight and aerodynamic Mavic Cosmic S 42 Carbon wheels matched with fast, grippy, and puncture-resistant Pirelli P-Zero Road tyres and a Ribble RI-2 integrated one-piece carbon cockpit that offers stealth cable routing and a drag reduction of 40% when compared to conventional handlebar set ups.

Groupset

Shimano Ultegra R8100 has been completely redesigned with all-new ergonomics, even greater brake modulation and wireless electronic shifting precision. It delivers the world’s fastest and most reliable wireless shifting and a wide gear range which means no matter how steep a climb is; it’s never outside your comfort zone. Di2 gives you instant, accurate, lightning-fast shifts every time at the push of a button. Even in the most extreme of conditions, shifting is precise and controlled. You can even change gear under heavy load while climbing or accelerating. With Di2, you are in complete control.

Wheelset

Mavic Cosmic S 42 Carbon wheels are engineered for riders seeking the perfect balance between weight, aerodynamics, and speed. Their minimal drag and low inertia design allows you to accelerate and climb faster, while holding higher speeds for longer. Paired with Pirelli P Zero Road tyres, which balance performance with durability, for both reliability and grip. The carcass features excellent puncture resistance while keeping weight low.

*This wheelset will be supplied with white or grey decals.

Handlebars

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.

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 SLR Boost saddle. Bringing high performance, comfort, and support to any endurance ride or race event, the SLR's neutral shape allows complete freedom of movement without compromising pedalling efficiency or power output.

Frequently Asked Questions

The Toray T1000/T800 carbon frame weighs 1200g and the forks 580g, for a combined total weight of 1780g (size medium). Complete build weights are; Sport - 8.65kg, Enthusiast - 8.60kg, Pro - 8.50kg.

Similarly to the SL R, the Ultra SL's construction features a bespoke blend of Toray T1000 and T800 carbon fibres. However, the SL R uses more T1000 fibre within its layup, making it slightly lighter (250g) and stiffer.

The frame is guaranteed against manufacturing defects for a period of 3 years. The standard manufacturer's warranty covers all other components.

The Ultra Aero handlebars are exclusive to the Ultra SL R and are only currently available on that particular bike model.

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

The Ultra SL has been approved to compete in UCI sanctioned events by cycling's governing body. 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 will result in disqualificaiton.

Yes. The Ribble RI-2 integrated carbon handlebars, in combination with the frameset, enable all the cables to be fully hidden, preserving the Ultra's super sleek lines for maximum drag savings.

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

All standard bottle cages and bottles are compatible; the Ultra SL is optimised to 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 M12x125mmx1.5 and M12x173mmx1.5 front and rear thru axles.

Due to the Ultra SL being a speed-centric aero bike, the frame isn't designed to accept mudguards.

We recommend a maximum rider plus bike weight of 120kgs.

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 mount it to the extensions themselves.

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

Due to the many different systems people use, we don't supply pedals with bikes. However, you can choose from a selection of the best-selling pedals when you configure your bike.
