Tour Pro Bike: Adriano Malori's Wilier Twinfoil

L’ALPE D’HUEZ, France (VN) — Wilier first debuted its new Twinfoil frame at the Giro d’Italia this year but appear to have made some significant updates since then.

A cruise through the team buses after Friday’s L’Alpe d’Huez stage unearthed this Twinfoil, with a radical split fork and integrated TRP front brake.

According to Lampre-ISD team mechanics, the only member of the team to use the new frame in Saturday’s time trial will be Adriano Malori, the current Italian time trial champion, former world U23 TT champion and last year’s lanterne rouge at the Tour. Malori’s backup bike will be the previous version of the Twinfoil.

The Twinfoil concept is predicated on the idea of moving frame elements farther away from the spinning wheels to minimize air turbulence and drag caused by wheel/frame interaction.

The new frame appears to have a similar main triangle with wide-set seat stays but with major modifications to the fork and head tube. The fork still uses wide legs as the old version did, but now includes split aerofoils up past the head tube to channel air around the frame.

A TRP front brake is integrated behind the fork to keep it hidden away.

Malori will run the new frame with a deep 80mm Fulcrum front wheel rear disc and 55-tooth big ring for Saturday’s test.
