Verdiktas
+Stiprybės
- 1,420 g (40C) verified actual — lighter than several rivals incl. Zipp 303 NSW clinchers; spins up fast for accelerations
- AC3 braking surface: powerful, consistent wet-weather braking that matches aluminium — rare for a carbon rim
- USB / CULT ceramic cup-and-cone bearings: buttery smooth, adjustable preload, fully serviceable, shared with Campagnolo Bora Ultra
- Italian hand-build with F.I.C. certification — perfect spoke tension out of the box, MoMag no-drill rim bed (no tape, no stress points)
- 40 mm 'Goldilocks' depth + V-profile: real aero gain yet stable in crosswinds and friendly on climbs
−Trūkumai
- 17 mm internal width (40C) is narrow by modern standards (20 mm+ now common) — creates a 'lightbulb' shape with 28 mm+ tyres
- Speed 40C is NOT tubeless despite an undrilled rim bed — 2-Way Fit certification absent ('missed opportunity')
- Premium price (~£2,000 for 40C clincher) buys full carbon disc wheels from competitors
- Disc variants' actual weight (~1,560 g measured) overshoots the ~1,460-1,470 g claim by ~100 g
- Now outclassed by its own 2024 successor Speed 42 (23 mm internal, 1,410 g, ratchet freehub) and not the fastest at equal depth vs Hunt 44 / Zipp 353 NSW
