The new Scope AEA-Disc and R9.T wheels
A new benchmark in aerodynamics

The wait is over, after 5 years of development Scope launches its Time Trial (TT) and Triathlon platform with the all new AEA – Disc and R9.T wheels, a new benchmark in aerodynamics, developed in partnership with the Scope development partners.

Based on knowledge from the World Tour peloton, we developed the fastest wheelset for realworld conditions, using an integrated approach by taking into account the complete system including wheels, tires, bike, and rider. The intense partnership and development process resulted in a wheelset bringing up to 8% reduction in drag and 3.5-watt reduction in rolling resistance. Applied to a Grand Tour time trial of 30 km this results in a half a minute time win. For a full triathlon (180km) this will add up to a saving of almost three minutes.

After numerous of test kilometers, we are excited for the debut of the AEA – Disc and R9.T in the World Tour peloton at the final Prologue in Copenhagen in this year’s Tour de France.

Real world data

As a base line for the development of the Scope Time Trial and Triathlon platform we made use of the “TT Real World Data”. The data of this research was conducted over the 25 most valuable time trails by a World Tour Team at the Grand Tours and World Tour races in the periode between 2017 and 2020. Derived from the study, the following conclusions have been our main develoment parameters.

  • The importance of aerodynamics in relation to rolling resistance.
  • The most common wind speed.
  • The Distribution of the incoming wind angles.

Rolling resistance vs aerodynamics

As a next step, together with our development partner Schwalbe we investigated the effect of wider tubeless tires versus aerodynamics. It was concluded that a 28 mm tubeless tire provided a significant reduction in rolling resistance compared to a 25 mm tire and allows to ride at a lower tires pressure providing additional comfort and grip.

However, since the aerodynamic penatly increases linear when the speed increases, and at the same time, the front wheel encounters non-disturbed wind flows whereas the rear wheel is already disturbed by front wheel, bike and rider, our studies concluded that for the front wheel a 25 mm, and for the rear wheel a 28 mm tubeless tire provides the optimul set up.

AEA Technology

Once the optimul tire width has been defined we started with the development of the rim profile making use of the Scope Algorithm Enhanced Aeorodynamics (AEA). Instead of approaching the optimul rim-profile by making use of Computational Fluid Dynamics (CFD) analysis, our algorithm exactly calculates the optimum rim-profile making use of the pre-set real world data settings, guarenteeing the best aerodynamic performance.

 

AEA

Benchmark Study



The first prototype’s have been tested in the windtunnel to verify the design and further study the interaction of the wheels with tires, bike, and rider. Furthermore a bechmark study has been performed of which can be concluded that the AEA – Disc provides up to 8% of reduction in drag, and the R9.T up to 4% reduction in drag. This makes the AEA – Disc in combination with the R9.T the fastest TT / Triathlon wheelset available.

AEA - Disc

R9.T

Developed as a system

Based on UCI World Tour riders input, besides the optimization in aerodynamics and rolling resistance, as well we have been focusing on overall efficiency of the wheels, and prevent them from being too harsh and unforgiving like most current TT wheels.

To guarantee the perfect balance between these variables, it was concluded that a cover approach should be the way to go intead of the conventional monocoque structure. For that reason, the Scope R4 rear wheel is used as a baseline for the new AEA – Disc, featuring the Scope Diamond ratchet hub-set with Ceramicspeed bearings, Scope tubeless system, and Local reinforcement carbon lay-up, providing the perfect balance between weight, laterall stifness and durability.

Optimized Aerodynamics

The rim profile of our wheels is developed using our Algorithm Enhanced Aerodynamics (AEA) technology. This algorithm calculates the most aerodynamic rim profile to ensure optimum performance.

Ultra-light and durable

The hubs feature our Diamond hardened Ratchet engagement System for direct engagement, improved durability, and a significant reduction in weight.

Lightweight

With our Local Reinforcement carbon technology we increase the number of carbon layers only around the spoke holes on the inside of the rim. This way we significantly reduce its weight, while preserving the strength and stiffness.

Perfect tire fit

The unique geometry of our Scope Tubeless System ensures easy mounting, direct inflation, long-lasting pressure and compatibility with all (tubeless) tires.

In partnership with DSM engineering materials different suitable cover materials and application methods have been studied, with the goal to reduce weight, while optimizing stability and shock absorption.

AEA

Developed in The Netherlands

With DSM’s wide range of material knowledge and application we have found a parnter who has been of great support in the develoment of the Scope AEA – Disc. We look forward to continue our partership enabling us to keep challenging ourselves and stay up to date with the newest materials and technologies for our future products.

Availability and future developments

Development never stops. Even though we do have some further ideas to improve the performance of the AEA – Disc and R9.T we have decided to launch the MK1 as per direct. By making it available for the professional and competitive cyclist we follow our mission to improve the riding experience and contribute to the ongoing battle for marginal gains.

For the time being all Scope AEA – Disc and R9.T wheels are hand-built by our engineers in the Scope Cycling Research Lab in The Netherlands. For that reason, availability is limited. In parallel, our engineers will continue their ambitions to further improve the set-up and make it available in serial production by 2023.

The AEA – Disc is available as per direct for a price of 2.198,- EUR, and the R9.T for 998,- EUR. To place your order, get in touch with our sales team via mail: [email protected] or via phone: 0031 (0) 402986604.
