Wilier launches new Supersonica SLR TT bike: Yours for a cool €27,400 in its top spec

Wilier claims that its new Supersonica SLR time trial bike was 16 per cent more aero than its previous time trial bike, the Turbine, when it tested the new bike at 50km/h wind speeds in the Silverstone Sports Engineering Hub wind tunnel, where Cyclingnews has tested aero road wheels and road helmets. 

The new bike has been developed alongside Swiss time trial champion Stefan Küng of the Groupama-FDJ pro team. The whole project has taken just nine months, including over 50 hours of CFD computer simulations, 30 hours of testing of 3D printed mock-ups in the wind tunnel, and the production of two prototypes. The Supersonica SLR has also been let loose in the Tissot Velodrome in Switzerland and on the roads of Belgium.

It’s the first bike that’s been developed by Wilier together with Groupama-FDJ since it took over from Lapierre as the team’s bike sponsor, although it’s clear that the change of bike provider to the team was in the works long before the official announcement in December 2023. Wilier has also been supplying Astana-Qazaqstan with its bikes since 2020.

Developments from the Turbine include an updated geometry, greater rigidity and an updated bar design, Wilier says. It doesn’t provide any raw data to back up its aero claims.
