StorckAerfast.5
Storck's aero road race bike in its top Team carbon grade. The Aerfast.5 launched in March 2024 with an 80 mm wide fork, a one-piece cockpit, a redesigned seat tube and seatpost and a claimed 890 g frame; Storck quotes 195 W at 45 km/h measured to TOUR's wind-tunnel protocol and says it is lighter and stiffer at the bottom bracket than the Aerfast.4. Sold direct in four groupset builds or as a frameset.

Our verdict
Overall
out of 100, average of 6 categories
Storck's top-carbon aero racer, among the fastest bikes TOUR has measured, sold direct with carbon wheels on every build. You pay a big premium over the identical-looking Pro for the Team carbon, get one cockpit size per frame and no power meter, and the seatpost rides harshly per reviews of the Pro.

Aerodynamics
TOUR measured an Aerfast.5 Pro at 198 W at 45 km/h in its 2025 comparison, a record in its testing at the time, and a later SRAM Red 1x Pro build was roughly one watt faster than the Stromm Raktt in crosswinds.
SourceFit
Storck's size guide gives rider heights of 152-166 cm (XS), 164-172 (S), 170-178 (M), 176-184 (L), 182-190 (XL) and from 188 cm (XXL).
SourceHistory
The Aerfast.5 was unveiled in March 2024 as Storck's new aero flagship, with a claimed 890 g frame and Storck billing it as the fastest road bike in the world. TOUR's own wind-tunnel measurement of the launch bike, set up 1x, came to 201 W.
SourceVersions
Team and Pro frames look identical and share geometry; Storck told TOUR that the EUR 1,600 surcharge for the Team over an identically equipped Pro is for higher-grade carbon.
