WORLD CLASS TT PERFORMANCE

Designed and perfected with ultimate watt-saving aerodynamic efficiency as the priority, the new Ultra TT is a bike bred purely to go fast. Raced by Ribble Pro Team riders, the Ultra TT is a UCI legal, proven race winning and record breaking TT platform.

The performance tuned, full carbon Ultra TT frameset has been aerodynamically optimised for real world racing conditions with built-in adjustability to enable you to achieve your perfect position.

TESTING, ANALYSIS & REFINEMENT

Fine-tuned through a rigorous testing process, this time trial superbike has been developed by our R&D team using the world class aerodynamic expert and UK time trial champion Dan Bigham as our test pilot.

Hours in the velodrome, real world testing and extensive CFD analysis repeatedly identified further aero gains throughout the R&D and prototyping process.

FOCUSING ON AERO DETAILS IN R&D

The Ultra TT bike’s multi-stage development process began during 2017 with the design brief to create a versatile World Class time trial and triathlon platform that would give our customers and Ribble Pro Cycling team riders a clear aerodynamic advantage over the opposition.

DRAG SAVE FINAL ANALYSIS

The final CFD and real world testing showed a total bike and rider drag saving of up to 2.2% and an average of 1.3% across a -15 to +15 degree YAW sweep versus initial prototype and benchmark.

TIME SAVINGS

Drag saving equates to up to 23 seconds based on our test rider racing a flat 25-mile (40.2km) at 29mph (46.6kph).

Watch Dan Bigham, holder of five National TT titles, testing the Ultra TT in early 2018.
RACE WINNING AND RECORD BREAKING

Our guiding aim whilst developing the new Ultra TT was to provide a world class TT and Tri platform for Dan Bigham, John Archibald and the Ribble Pro Cycling team, as well as our customers - a bike faster than any other TT bike they had raced before and the results of the analysis show that we’ve succeeded.

The Ultra TT is an uncompromising, speed centric platform designed to allow you to reach your full potential. The new Ultra TT is an innovative tech loaded speed machine.

Making the jump from the established high level TT bike I rode last season was always going to be daunting but Ribble have put the groundwork and R&D in to bring the team a bike that is able to take on the best

Our testing shows we are right on the money and will be able to continue to challenge for the win at both domestic and international time trial competitions. - Dan Bigham, 5 Times British National Time Trial Champion

KEY PERFORMANCE FEATURES

Fit range and adjustability: The frame geometry is designed to give riders a more aerodynamic position to maximise time trial performance. The Ultra TT offers a great range of adjustability and is compatible with all aftermarket multi position aero bars and cockpits allowing you to dial the cockpit to maximise your aerodynamic efficiency. To further fine tune your perfect fit the aero seat post of the Ultra TT enables a wide range of effective seat tube angles from 76 to 79 degrees for your preferred position.

Optimised frame design: The Ultra TT frame set has been dialled to offer the perfect balance between aerodynamics, rider positioning, handling and control. The high grade, unidirectional carbon Ultra TT frame has been optimised for maximal power transfer and compliance where required. Rear facing drop outs take the rear wheel of the Ultra TT as close as possible to the seat tube to create a shorter, stiffer rear triangle and improve the airflow from the seat tube and over the rear wheel. This also allows adjustment of the wheel for tyres up to 25mm width.

Maximal aero gains: Every aspect of the Ultra TT has been optimised for performance. From the TT specific, full carbon fork providing precise steering, control and featuring truncated Kamm-tail aerofoils, the truncated aerofoil frame tube profiles and seat post through to the rear seat stays designed to sit in the shadow of the front fork. To maximise every advantage the front and rear brakes mount behind integrated, streamlined aerofoils with all cables hidden from the airflow further optimising the drag reduction of bike and rider.

Frequently Asked Questions

Q: Are the Ultra TT and Tri suitable for non-elite racing?
A: Although the frames are race specific and have been designed with high end performance in mind because they allow a wide range of adjustability they are perfect for all time trial distances and non-drafting standard, middle and long-distance triathlon. In order to achieve a low, aero position, those not used to racing in this position may experience strain on the lower back and neck initially, but a less aggressive fit is also achievable. The Ultra TT will ensure that all riders maximise their performances, there will be no excuses!
Q: What are the key differences between the TT frame and Tri frame?
A: The two frames are almost identical and both benefit from the same aerodynamic optimising development and testing process. The Ultra TT comes complete with two aerofoils fitted over the front brake whilst the Ultra Tri has a drink box mounted in that position. The Tri specific model has been designed to include three aerodynamic secure (but detachable) feed/storage units so you can focus completely on your own performance. The rear box can also be used as an emergency tool storage unit if you experience a mechanical and fits to both models.
Q: What are the capacity of the feed boxes?
A: Front hydration system: 500ml (400ml Extra Small frame). Top Tube box: 150ml. Rear box: 500ml.
Q: What does the frame weigh?
A: 1.2kg.
Q: What is the widest tyre that can be fitted?
A: The rear facing horizontal drop outs allow space for tyres up to 25mm width.
Q: Is the frame compatible with other brands of stem and bar extensions?
A: Yes, the forks have a standard steerer and the front end of the bike is designed to take any standard handlebars and stem.
Q: Would a bike fit be required?
A: If you’re serious about racing then a final position fit is advisable once you’ve identified the frame size for you. Getting fitted may be beneficial to prevent injury and ensure the bike works with you, helping you to generate as much power as possible when pushing for those extra time gains. Ribble are on hand to advise on the correct size of frame, or if you prefer, you can visit one of our showrooms to size up against the bike.
Q: Does the bike come with pedals?
A: No, pedals are a personal choice. We offer a wide range here.
Q: What is the warranty of the frame and what does it cover?
A: The frame has a three-year warranty against manufacturing defects. All other parts have the manufacturer’s standard warranty.
Q: Is the bike built with stem stackers?
A: Builds that have the Zipp SC SL stem will have 30mm stem stackers. Builds that have the USE stem won’t have stem stackers as they have adjustable elbow rest heights.
Q: How much height adjustment is there with the USE Tri-bar set?
A: The USE Tri-bar set comes with 4x10mm and 2x20mm stackers. This gives multiple stack height options up to a maximum stack of 40mm under each arm-pad. The arm pads are also laterally adjustable.
Q: What sort of BB does this frame have?
A: The frames requires a press fit BB30 68x46. We fit our own Ribble cups when fitting Shimano chainsets.
Q: What is the total weight of bike?
A: Our Dura Ace Di2 edition weighs 8.5kg.
Q: Can I have a 39/53 chainset?
A: If the build you are looking for is not available, get in touch and our experts can take a look at your exact requirements.
Q: Will a 4iiii Powermeter fit?
A: Yes
