Cinelli has plenty of history when it comes to racing and aerodynamics. While the Milanese manufacturer is best known for its classic steel bikes and components, it's been storied in racing since its formation in 1948, with 1981's Laser widely considered the first aero road bike.
The Aeroscoop is unlike other aero bikes on the market, such as the radical Factor One and Ridley Noah 3.0.
With a generous 34mm tyre clearance, it retains mostly ‘normal’ tube dimensions. But the distinctive split-seatstay design certainly stands out, and is claimed to condition turbulent air in the same way the Trek Madone’s IsoFlow seat tube does.
In fact, the Aeroscoop was deemed 5W faster (on average, at 45kph across -20 to 20 degrees of yaw) than a Specialized Tarmac SL8 in independent wind-tunnel testing carried out by Germany’s Tour magazine.
While I’ve got some reservations about the fit (although I’m at the extreme end of the available sizing), the Aeroscoop could be the under-the-radar aero all-rounder to beat in 2026.
Cinelli Aeroscoop what you need to know

- Double-arm seatstays stand out from the crowd
- 34mm tyre clearance
- 950g frame with SRAM UDH dropout
- Pure race geometry with a short wheelbase
- Columbus Spirit one-piece carbon cockpit
- Specced with a Shimano Ultegra Di2 R8100 groupset
Cinelli Aeroscoop performance
The Aeroscoop’s ride is compelling and quick with reactive handling. It makes mid-corner corrections easily, and emergency reactions such as avoiding a pothole are instant.
The combination of the short wheelbase (1,011mm on my size-XL test bike) and 410mm chainstays with a steep 73.5-degree seat angle and 59mm fork trail contributes to giving the Aeroscoop a true race-bike feel.
While the frame and fork are noticeably stiff, this stiffness is thankfully offset well by the generous 32mm Schwalbe One tyres, which come up slightly larger at 33.3mm on the Mavic Cosmic S 42 wheels with their 21mm internal width.
The larger volume does an excellent job of reducing road chatter and doesn’t compromise the Aeroscoop’s acceleration and ability to hold a solid pace, while the Prologo Dimension saddle and supple bar tape boost the bike’s comfort further.
The XL frameset is the largest size offered and comes with a 575mm effective top tube length, which felt a little short for my 6ft 2in height. I also felt cramped by the combination of the 402mm reach and 583mm stack.
That’s further compounded by the narrow 41cm bar (measured, outside to outside). While the Columbus Spirit integrated cockpit’s 120mm stem length should be ample, I wanted a little more room to move on longer rides.

While I appreciate the trend for narrow handlebars in terms of aero efficiency, they’re not for me. On the hoods, I found the steering compromised, which makes the bike less stable and somewhat twitchy. I’d like it if Cinelli offered options on the cockpit because I’d like to try the Aeroscoop with a wider 42cm bar.
That said, I love the chamfered shape of the bar’s drops – it puts your wrists in an ideal position, and I found I stayed down in the drops much more than being up on the hoods.
Where the Aeroscoop really impresses is on long stretches of rolling terrain, with the low stack and ergonomic drops making for a wind-cheating position that feels efficient – I particularly enjoyed the bike on my longer rides, even with those fit reservations.
Shimano’s Ultegra Di2 groupset is as good as ever, and the 50/34t crankset, combined with an 11-34t cassette, offers an excellent gear range. The Ultegra brakes are excellent too, providing the right balance of power and feel, and they stayed quiet in all weathers.
While the Mavic Cosmic S 42 wheels are of a middling weight for carbon, at 1,660g, they're a solid choice on a bike at this price, with a good ride feel that's stiff under sprints.
At £5,299 / $8,399, the Aeroscoop Ultegra Di2 model compares favourably to the competition. You'll pay £7,249 / $8,499 for a Specialized Tarmac SL8 Pro (also with Ultegra Di2 and carbon wheels), £7,250 / $8,999 for Trek’s Madone SLR 7 Gen 8 and £5,995 / $6,499 for Cannondale’s latest SuperSix EVO 2 in a similar build.
It also undercuts Italian rivals such as the Pinarello F7 Ultegra Di2 at £6,500 / $8,799 and Bianchi’s Specialissima Pro Ultegra Di2 at £6,990 / $7,900.
How I tested the Cinelli Aeroscoop
I rode the Aeroscoop over three months in all weather and on a variety of roads, from straight and fast dual-carriageways to twisty rural roads in rolling south-west Wiltshire.
The tarmac varied in quality from fresh and smooth roads to pothole-strewn and frost-scarred surfaces on a mix of short one-to-two hour blasts, through to four-to-five hour endurance days out.
Cinelli Aeroscoop bottom line
I like the Aeroscoop and its distinctive styling that combines aerodynamics with aggressive race geometry. Fortunately, its stiff and responsive frame doesn’t come at the expense of comfort, thanks to great contact points and big-volume tyres.
I found the ride position a little short for my proportions, and it would be great if Cinelli offered a larger size than the XL, or perhaps more cockpit choices.
With a keen price and high-quality spec, I’d have no hesitation in recommending the Aeroscoop if the sizing suits you and you’re looking for a race-ready ride that stands out from the crowd with balanced comfort and fast handling.
