Description

With its innovative design and aerodynamically optimised frame and forks, the Ultra SL is designed to dominate and deliver a blisteringly fast ride that will blow your mind. The serious racer or speed-obsessed road rider will appreciate a build that includes the slick and intuitive gear shifting of Shimano’s latest 105 2x12-speed mechanical groupset and the smooth-rolling performance of Mavic Ksyrium 30 Disc wheels paired with fast and grippy Pirelli P Zero Road tyres. Rounding out this race-ready build is a set of RI-2 integrated carbon handlebars, complete with stealth cable routing to keep cables entirely removed from airflow. All contribute to a slippery frame profile that helps the Ultra SL generate up to 40% less drag than conventional handlebar setups.

Groupset

Shimano’s first and only 12-speed mechanical groupset is the latest addition to the premium road family. 105 7100 combines pure cycling with pure craftmanship. Inspired by 105 Di2, this versatile drivetrain delivers the wide gear range, hand-friendly ergonomics and all-condition braking confidence you’ve always craved. Developed from Shimano’s Science of Speed philosophy, 105 mechanical raises accessible performance to a whole new level.

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 grip. The carcass features excellent puncture resistance while keeping weight impressively low.

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 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 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 120 kg.

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.

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.
