Introducing Anemoi Mk2 – the evolution of cycling extension excellence. Building upon the original Anemoi extensions that set the industry standard, we've taken innovation to the next level with our latest iteration.

In response to the ever-changing UCI regulations and the evolving needs of triathletes, we've gone back to the drawing board to refine and optimise the original design. The result is Anemoi Mk2 – a product that stays true to the essence of its predecessor while introducing ground breaking features and advancements.

With Anemoi Mk2, we continue our commitment to evolution, not revolution.

Why we created Anemoi Mk2

The Anemoi Mk2 Extension System is a testament to our dedication to evolutionary progress rather than abrupt revolution. Rooted in extensive research and customer feedback, numerous upgrades have been meticulously crafted to enhance every aspect of the system. From versatile mounting solutions and robust hardware to updated profile designs and numerous handgrip options, the Mk2 upgrades are abundant.

Amidst the refinements introduced across various aspects of the Mk2 System, certain features endure. The highly sought-after Anemoi Adjustable Riser, favoured by those valuing customisation, retains its prominent place. Additionally, the Anemoi Carbon arm rests, renowned both as standalone items and integral components of the Anemoi system, persist with subtle tweaks aimed at achieving the optimal position.

For more details on the latest system enhancements, refer below or delve into our performance blogs to explore the ongoing evolution of the Anemoi System.

Mono Riser Stack Mount Options

The Mono Bracket is an integral part of the system, ensuring the Anemoi Extensions' compatibility with various basebars with mono riser systems. Our ever-expanding collection of Mono Brackets now cater to the vast majority of market-leading mono riser systems. 

Brackets are available in five different reach sizes from XS (extra short) through to XL (extra long). The size required is determined by your bottom bracket to extension tip and bottom bracket to rear bolt hole dimensions.

Please refer to our Build Guide for further guidance on selecting your size. 

New Features

Extension Profile

Taking advantage of recent UCI regulations, our widened 46mm cross-section extension profile provides enhanced forearm support while simultaneously reducing drag resulting from boundary layer separation. Wider extension profiles were consistently faster in our wind tunnel and velodrome tests. The Mk2's aggressive new wrist kink also minimises the gap between the extension and wrist, mitigating localised flow turbulence.

Handgrip Options

Introducing the Anemoi Mk2 interchangeable handgrip collection to suit various shifting systems. A sophisticated two-piece design with integrated satellite shifters, these grips optimise shifter contact area. The expanded contact surface ensures effortless shifting, whether using your index finger, little finger, or a full palm grip. An enlarged handgrip hardpoint offers greater access to the extension for junction boxes and cables. Please check our Build Guide to ensure UCI compliance.

Computer Mount

The Mk2 System debuts two new Computer Mount designs. A single-sided option suited to uncontrolled lateral centres introduces toe adjustment and allows you to align your Garmin or Wahoo irrespective of the extension toe angle. A crossbrace version is also available and suited to the Anemoi Basebar and Conversion Spacer mount options. This innovative design centralises the head unit and creates a sturdy bridge between extensions.

Adjustability

Retaining all of the adjustability of its predecessor, the Mk2 System now offers up to 35mm of reach adjustment, while our redesigned Puck allows for up to 5º of toe-in and 10mm of lateral width adjustment for a truly tailored fit. A more elevated extension angle in front of the armrest provides superior forearm support and a more ergonomic high-hands position.

Reduced Stack

By reducing the stack height under the armrest by 4.5mm, we've achieved significant gains in aerodynamic efficiency. Additionally, the option to remove the mount plates allows for a total possible stack height reduction of up to 12.5mm. This not only streamlines the profile for enhanced aerodynamics but also offers greater customisation options, allowing riders to achieve their ideal fit with precision.

Compatibility

The continuously expanding collection of Anemoi Mono Riser Brackets are engineered to cater to the diverse landscape of mono riser systems. Facilitating seamless integration between your existing basebar and the Anemoi system, these brackets offer a harmonious interface. Brackets are compatible with both systems, ensuring an effortless transition for riders who are upgrading to the Mk2 System.

Fixed Angle Risers

Pushing the boundaries of integration, our Fixed Angle Risers represent a new chapter in WattShop's product design innovation.

Available in 5º increments ranging from 10º to 30º, these fixed risers seamlessly integrate the extension arm with the mounting stack, creating a sleek and cohesive profile.

Ideal for riders confident in their preferred armrest angle, our wind tunnel tests have demonstrated that the fully integrated fixed riser design offers substantial CdA improvements.

Improved aerodynamic performance

Through exhaustive CFD, wind tunnel and velodrome testing, the Mk2's broader extension profile consistently showcased aerodynamic superiority, yielding repeated improvements in CdA.

After evaluating numerous profile designs, the ultimate Mk2 iteration, represented by Profile F in the graph below, emerged as the top performer on average. While certain profiles may have surpassed it for individual riders, our comprehensive testing consistently demonstrated that the selected profile exhibited superior performance across various conditions and riders. The significant enhancements compared to the Mk1 system can be seen below. Please check out our Performance Blogs for more information about the testing process.
