CerveloS5
Algupära
Cervelo S-seeria ulatub tagasi 2011. aastasse, kui S5 turule toodi kui puhtalt aerodünaamiline maanteeratas, mis asendas algse Soloist sarja. Cervelo enda tuuletunnelist pärinevate andmete põhjal konstrueeritud S5 oli tuntud oma agressiivse kamm-saba kujuga raami ja polariseeriva V-varre poolest, millest sai selle visuaalne tunnus. 2025. aasta põlvkond, mida Jonas Vingegaard Visma-Lease a Bike meeskonnas sõitis, loobus V-varrest üheosalise HB19 kabiini kasuks, millel on Plus-Four laienemine, suurendas rehvide kliirensit 29-32 mm-ni ja väidetavalt säästab 6,3 vatti kiirusel 45 km/h võrreldes eelmise mudeliga, kui seda kasutatakse koos sobiva Reserve rataste komplektiga. See jääb brändi kompromissituks aerodünaamiliseks lipulaevaks ja rattaks, mille poole Visma sirutab käe nii munakivisillutise kui ka mäetippude finišite jaoks.

Verdikt
- Among the fastest aero road bikes ever lab-tested (BikeRadar/Cyclingnews); claimed ~6.3 W saving at 45 km/h over the previous gen with matched Reserve wheels
- Lighter than the outgoing S5 (~124 g lighter frameset) yet very stiff — genuine do-everything race bike Visma riders pick even on mountain stages
- Modern 34 mm tire clearance and swappable-setback SP34 seatpost — far more versatile than older aero superbikes
- Stable, predictable handling and confident cornering thanks to consistent 405 mm chainstays and low BB
- HB19 cockpit with flared Plus-Four drops gives extra control on fast descents
- Very expensive — flagship Dura-Ace build ~€14,000, and even the frameset entry point is ~€6,000
- Ride feel is calm/placid and somewhat disconnected from the road; lacks snap at low speed and needs rider input to come alive
- Deep rims + wide flat aero tubes make it noticeably twitchy in crosswinds, pushed sideways even by light gusts
- Integrated HB19 cockpit is not swappable at purchase — changing fit means buying a whole new one-piece bar/stem
- Stock 54/40T chainrings are overgeared for most amateur riders, and seatpost setback can't be changed for free at point of sale
