S5
vsPinarello F
The wind-tunnel weapon vs. the Dogma understudy.
The Cervélo S5 is a system built around one thing: speed above 35 km/h. The Pinarello F is the Dogma F's cheaper twin — same geometry, same handling, lower-grade carbon.
S5
- Wind-tunnel-validated speed — Cervélo's published numbers put this S5 about 6 watts faster than the previous generation at 40 km/h.
- Co-developed wheel and cockpit system — Reserve 57|64 wheels and the HB19 carbon cockpit are speced on every build, top to bottom.
- Wider tire clearance than Pinarello — 34 mm claimed, ships with 29 mm Vittoria Corsa Pro on wide internal-width rims.
- Price floor is $10,100 — no entry-level builds at all.
- Reviewers consistently flag toe overlap and a stiff, demanding ride at slow speeds.
Pinarello F
- Dogma-F geometry without Dogma money — same 47 mm fork rake, same E-TICR headset, same handling reviewers call "a motorcycle with pedals."
- Wide build range from $3,500 up — the only one of these two with a 105 mechanical entry point.
- Nine frame sizes vs. Cervélo's six — meaningful for riders at the tails of the bell curve.
- Lower-tier builds carry a real weight penalty — the F3 105 Di2 hits 8.5 kg.
- Tire clearance caps at 30 mm here (32 mm on the F9), narrower than the S5.
Editor’s analysis
This isn't aero vs. lightweight — it's purpose-built race tool vs. near-flagship at a fair price.
The Cervélo S5 and the Pinarello F sit in the same race-bike conversation but answer different questions. The S5 is a dedicated aero platform — Cervélo hired a wind tunnel and reportedly measured it as the fastest production frame they've ever tested at 40 km/h, with the new HB19 cockpit and Reserve 57|64 wheels co-developed as a single system. The Pinarello F is a different proposition: borrow the Dogma F's geometry, fork rake, headset, and aero keel BB, then mould it from one carbon grade down (T900 instead of T1100) and sell it for thousands less.
Where the bikes diverge sharpest is in their build ladders. The Cervélo S5 starts at $10,100 and tops out at $14,500 — every build is electronic, every build comes with the same Reserve wheels and HB19 cockpit. The Pinarello F starts at $3,500 with mechanical 105 and stretches to $11,000 for the F9 Dura-Ace Di2 — three times the price band, four times the entry-point spread. If your budget is under $8k, this isn't really a choice; the S5 doesn't sell there.
The geometry tells the same story in subtler ways. At the fit-picked sizes for a typical rider — size 54 on the Cervélo S5, size 500 on the Pinarello Pinarello F — stack and reach are within a millimetre of each other (542/384 vs. 542.6/385.6). What differs is the head angle and chainstay: the S5 runs a 73° HTA with 405 mm stays; the Pinarello F sits at 72.5° with 408 mm stays. Subtle, but reviewers describe the Pinarello as feeling "glued to the road" on switchback descents while the Cervélo S5 reads as more demanding — Bicycling's Tara Seplavy explicitly found the S5 "trickier" on fast downhill turns than other race bikes.
Put plainly: if most of your riding is flat or rolling and you race for the average-speed PR, the Cervélo S5 will measurably pull you along. If you want a near-Dogma ride with the option to start at a 105 mechanical price point — and you'd rather have the more confidence-inspiring descender — the Pinarello F is the more honest value.
Where the builds differ.
Comparing our editor's-pick builds side-by-side. Winners highlighted row-by-row — lower price and weight, and the better-spec component, each mark a point.
Build variants & pricing
Tier-matched at Ultegra Di2 — but the Cervélo S5 starts $1,900 above the Pinarello F at the same drivetrain spec, and offers no builds below $10k at all.
Prices are current US MSRP. The Pinarello F's lower-tier builds (F5 105 Di2 at $4,500, F1 105 at $3,500) have no equivalent on the S5 — Cervélo's lineup is electronic-only and starts at $10,100. If your budget is under $8k, the comparison effectively ends there.
How they fit, how they steer.
Cervélo S5 size 54 vs. Pinarello F size 500 — fit-picked for the same default rider. Stack and reach come within a millimetre, but the Cervélo S5 runs a half-degree steeper head angle (73° vs. 72.5°) and 3 mm shorter chainstays. The Pinarello is the more stable platform; the Cervélo S5 the sharper one.
Which size should I buy?
The Pinarello F offers nine sizes against the Cervélo S5's six, with stack and reach overlap across most of the middle range.

Which one should you buy?
If you race flat-to-rolling above 35 km/h and can spend $10k+, get the Cervélo S5. If you want Dogma-F handling at a real-world price, get the Pinarello F.
S5
If most of your riding is flat or rolling and you race above 35 km/h, the integrated wheel-and-cockpit system measurably drags you forward. The climbs will hurt more — and the flats will hurt the field. Bring the budget; there's no entry-level pricing here.
Pinarello F
Pinarello kept the Dogma F's geometry and dropped the price by carbon grade alone — F9 buyers get "a Dogma in all but name," and even the F3 carries the same handling DNA. Pick this if you value confidence on technical descents over flat-road aero gains, and if a $3,500 to $11,000 build range matters to you.
Questions buyers actually ask.
Short answers to the things we get emailed about most often.
01Which is faster on flat roads?
The Cervélo S5, with the most published wind-tunnel data of any bike in this conversation. Cervélo claims the new S5 is roughly 6 watts faster than the outgoing generation at 40 km/h, and Cycling News' independent wind-tunnel test recorded it as the fastest bike they've ever measured with a rider onboard.
Pinarello publishes far less aero data on the F series — the engineering language is around "slimmer headtube" and "aero keel BB," not specific watt-savings. On a flat 40 km effort, expect the Cervélo S5 to hold a meaningful margin.
02Which descends better?
Reviewers favor the Pinarello F. Bike Rumor described it as "stable, stiff, and surprisingly comfortable" on classic switchback descents, and the design philosophy — borrowed wholesale from the Dogma F — is repeatedly called "a motorcycle with pedals."
The Cervélo S5 isn't a bad descender, but Bicycling's Tara Seplavy specifically called it "trickier to handle on fast downhill turns than some race bikes." The Pinarello's slightly slacker 72.5° head angle and 3 mm longer chainstay give it more high-speed composure on the way down.
03What's the maximum tire clearance?
Cervélo S5: 34 mm officially, though one reviewer was "sceptical" of that number and found 32 mm tight in practice. Stock builds ship with 29 mm Vittoria Corsa Pro on wide internal-width Reserve rims.
Pinarello F: 30 mm on the published spec for this generation, with the higher-tier F9 noted in reviews as accepting up to 32 mm.
Neither is a gravel bike — for chip-seal and rough roads the Cervélo S5 has a small edge, but only a small one.
04Is the Pinarello F really 'just a Dogma'?
Closer than you'd expect. Pinarello uses the same E-TICR headset, the same 47 mm-rake Onda fork, the same identical geometry as the Dogma F. The F7 and F9 are moulded from Torayca T900 carbon — one grade down from the Dogma's T1100, and roughly within 100 g of the flagship frame.
The lower-tier F5 and F1 use T700 and T600 carbon respectively, with a corresponding weight penalty (the F3 105 Di2 hits 8.5 kg). So "Dogma in all but name" applies most cleanly to the F9 and F7.
05Can I get either bike with a 1x drivetrain?
The Cervélo S5 offers a SRAM Red XPLR AXS 1x build at $14,500. Cervélo claims a 2-watt aero gain from removing the front derailleur, but reviewers (notably Bicycling's Tara Seplavy) found the gear jumps frustrating on climbs — a common 1x-on-the-road complaint.
The Pinarello F is 2x only across the entire range. If a 1x road setup is non-negotiable, only the Cervélo S5 ships it from the factory.
06How serviceable are the integrated cockpits?
Both run one-piece bar/stem units with internal routing — neither is a quick swap.
The Cervélo HB19 has been called "considerably simpler to maintain than its predecessor" thanks to easier headset access, and Cervélo gives buyers 60 days to swap the cockpit for a different size at no charge — a real concession given how locked-in these systems usually are. Note that the proprietary BBright press-fit bottom bracket houses the Di2 battery and is widely cited as a service hassle.
The MOST Talon integrated cockpit on the Pinarello is similar in concept; reviewers describe it as "stealthy and stiff." Like the Cervélo, post-purchase length changes mean a new unit.
07Which has the wider size range?
The Pinarello F offers nine sizes, from a 425 (502 mm stack, 351 mm reach) up to a 580 (633 mm stack). The Cervélo S5 offers six, from 48 to 61. For riders at the small or tall end of the bell curve, that difference is meaningful — Pinarello's range is one of the widest in the road race category.
08Which holds resale value better?
Pinarello's reputation on the used market is strong — one reviewer specifically cited "good resale value" as a factor in the F's value proposition. The brand carries a more exclusive perception, and production runs are smaller.
Cervélo S5s also hold value reasonably well in the aero-bike segment, but the Pinarello name — and the proximity of the F to the legendary Dogma — historically commands a slight premium on the resale market.
