Wilier TriestinaTurbine SL
Wilier's more affordable, triathlon-focused Turbine, shaped using lessons from the Supersonica SLR. It has a taller stack than Wilier's race TT frames, a steep effective seat angle (79.5° in size M) and a lowered bottom bracket. It comes with a Deda aluminium aerobar and a Profile Design top-tube toolkit. An optional Aerokit adds up to 1,100 ml of aero hydration. The frame takes 32 mm tyres, has a UDH dropout and a removable front-derailleur hanger, and is built for electronic groupsets.

Our verdict
Overall
out of 100, average of 7 categories
An approachable, UCI-legal tri bike for age-groupers who want a steep, comfortable long-distance position and standard parts that are easy to swap and service. The alloy aerobar and 105 Di2 build hold it back on speed and kit, and the aero hydration that makes the most of the frame is an extra purchase.

Design
Wilier describes the Turbine SL as a direct spin-off of the Supersonica SLR project, aimed at making a fast tri bike more accessible.

SourceIntegration
A 290 cm³ Profile Design ATTK toolkit comes standard. With round bottles the frame carries 550 ml on the down tube and up to 750 ml on the seat tube.
SourceCompatibility
It clears 32 mm tyres, has a UDH dropout, and the front-derailleur hanger can be removed for a quick switch between 1x and 2x electronic drivetrains.
SourceRacing
