Compatibility Guide & Technical Resources

BASEBAR WINGS ARE MADE TO ORDER. PLEASE ALLOW 3-4 WEEKS LEAD TIME.

UPDATE 19.09.25. We have updated the stem design to increase compatibility with frames with a deeper headtube. Headtube clearance up to 46mm is now compatible. This has necessitated a 10mm increase in stem length. At this time, the update has only been rolled out to the "long" stems. For the short and medium stems, please minus 10mm from the indicated stem lengths or use the archived basebar build guide for reference.

The Anemoi basebar represents three years of dedicated development, delivering unparalleled aerodynamics and adjustability.

The evolution of bicycle cockpit design extends beyond just extensions; the basebar presents a significant opportunity to minimise total system drag. With the Anemoi basebar paired with our Anemoi Extension System, we proudly offer the most aerodynamic and adaptable front-end solution available.

Supplied to the top of the riser stack, the Anemoi basebar allows for seamless integration with either the Anemoi Extensions or the Minimoi cockpit. The Minimoi cockpit includes adjustable risers, pole clamps, carbon armrests, and Minimoi extensions, facilitating easy upgrades for current Anemoi & Minimoi users.

If you require the adjustable angle risers, extension clamps, extensions or arm rests, please purchase these separately.

UPDATE 25.11.24. The carbon TT wings have been updated and are now manufactured in an alloy using the latest 3D printing technology. This allowed us to reduce the total weight with an optimised internal honeycomb structure. The finish is black anodised.

As part of the update, we now also offer a track specific wing profile.

WHAT COMPONENT PARTS DO I REQUIRE?

If you are not using the Anemoi Extension System, you can determine your stem based on the stem length dimensions indicated. A standard cockpit will retain fore-aft adjustment with the poles/pole clamp. However, you may still find the build guide useful for dialling in your optimised setup.

If you are using the Anemoi extension system, please refer to both the extension and basebar build guides. There you will find the relevant dimensions for both, ensuring you can select the correct componentry to meet your needs.

Once you have decided on your setup, you can select the relevant component options from the selection boxes. Answering one box will unlock the next round of selection boxes. If you need assistance, please email us info@shopforwatts.co.uk.

WIND TUNNEL DATA

Utilising the Silverstone Sports Engineering Hub wind tunnel, we tested the Anemoi Basebar against the Dare basebar, the PRO Missile Evo and the 3T Aduro. All set ups utilised the Anemoi extension system with the extensions set at 20 degrees. The reach and stack of the set up was kept the same across all test runs and an independent test rider was supplied by SSEH.

Results from our SSEH wind tunnel tests are presented in the graphs. There are four graphs; weighted CdA across various wind conditions, CdA plot from 0-15 degrees of yaw, wattage delta and seconds saved per km, all at 50km/h. For further graphs and data at 40km/h and 60km/h check out our Optimisation & Testing blog. If you would like any further information or data from the test, please get in touch.
