Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Favero Assioma DUO-Shi

Season:2024

Brand:Favero

Code:772-02-S

Overview:

•Designed for the compatibility with Shimano®road
Assioma DUO-Shi has been designed for Shimano®road users, as it offers the opportunity to keep on riding with your current Shimano®pedal bodies* without giving up on the trustability and precision of Assioma.

•Installation into your own Shimano®pedal bodies
Installing Assioma DUO-Shi into your own compatible Shimano®pedal bodies* is simple and quick. Watch ourvideo of the installation.

•*Compatible Shimano®pedal bodies
Assioma DUO-Shi is compatible with the following Shimano®pedal bodies: PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540.

•Increased Q-factor?
The Q-factor of Assioma Look® version is of +54mm, whereas that of Assioma DUO-Shi measures +64mm with the PD-R7000/R550/R540 pedal bodies and +65mm with the PD-R8000/6800. Despite an initial concern related to the increase of the q-factor, we decided to proceed with the project considering that body size (height, pelvis width, etc.) is a subjective factor contributing to determining which is the best q-factor for each one of us. A final, positive feedback from our beta testers has eventually validated the product.

•Easy to install
Install and transfer your Assioma from one bike to another just like normal pedals, easily and without extra tools. Just screw them on your bike crank arms and you are ready to pedal!

•IAV Cycling Dynamics
Assioma supports the advanced metrics IAV Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data, allow analyzing in details the pedaling technique and how the cyclist's position on the bike influences performances.

•IAV Power and gyroscope
Unlike others, the measurements of Assioma are not affected by errors related to very irregular pedaling (eg. sprint uphill) or the use of oval chainrings. This is because Assioma is able to detect the actual instantaneous angular velocity of the pedal stroke, thus giving you the degree of accuracy of ±1% in any situation. Not only in the laboratory.

•Bluetooth and ANT+ SMART
Assioma communicates via Bluetooth and ANT+ with bike computers and smartphones, both Android and iOS.

•Real dual-sided power data
Assioma DUO provides dual-sided data through real measurements: taken individually on both the left and the right leg; this make it possible to observe with accuracy not only the Total Power, but also the L/R Balance, the Torque Effectiveness (TE), the Pedal Smoothness (PS), etc.

•Accuracy and consistency
Assioma provides accurate watt measurements with a great consistency and stability in the actual on-road use conditions and at any temperature between -10°C and 60°C. Thanks to the ATC (Automatic Temperature Compensation) too.

•Waterproof, resistant and light
The power sensors are protected in a bi-component resin block, extremely resistant to shocks and completely waterproof.

•Rechargeable and green
Assioma is the only pedal-based power meter with integrated rechargeable batteries; a single charge ensures 50 hours of use at least.

•Tested and guaranteed
Favero Electronics produces in-house each Assioma and thoroughly test it individually: fully satisfying the standards required by current regulations.
