There's a version of the Cinelli Aeroscoop Shimano Di2 Custom Bike for every rider who values precision over compromise. Cinelli's fastest road frame — Columbus T1100 carbon, wind-tunnel tuned to 205 watts at 45km/h, UCI approved — paired with Shimano's most proven electronic drivetrain system. The result is a bike that brings Milanese design conviction together with the shifting reliability that has defined professional road cycling for over two decades.

Cinelli built the Aeroscoop to compete with the best aero road platforms available. The airfoil-inspired tube profiles, double-arm seat stay design, and fully internal electronic routing aren't aesthetic decisions — they came out of actual wind-tunnel development. This is what Cinelli's fastest road bike looks like when they take aerodynamics seriously without letting go of the brand identity that makes a Cinelli unmistakable.

Columbus T1100 Carbon Frame

The Aeroscoop is built from Columbus carbon monocoque T1100 — a high-performance specification with a modified layup developed specifically for this frame to balance aerodynamic performance, ride quality, and real-world durability. The frameset weighs 950 grams in size M, with a full carbon monocoque fork at 370 grams uncut. The fork runs a 1-1/8-inch to 1-1/2-inch steerer with fully internal cable routing, flat mount disc brakes accepting rotors up to 160mm, and 12x100mm front / 12x142mm rear axle standards.

The included Columbus Spirit carbon handlebar and Columbus carbon seatpost are spec'd by Cinelli for this frame — they're part of the frameset, not additions. Handlebar width is sized to the frame: 360mm for XS, 380mm for S and M, and 410mm for XL. The seatpost offers 0 or 10mm offset. The IS52 headset is also included.

T47 Bottom Bracket & Full Internal Routing

The BB shell is T47/86 threaded with ceramic bearings included. T47 provides the stiffness advantages of a large-diameter shell with the reliability and serviceability of a threaded interface — no press-fit noise, no unpredictable creak, and straightforward maintenance. Shimano's Hollowtech II crankset is compatible with T47 via available threaded adapters, keeping the build clean and service-simple for the long term.

Cable routing is fully internal and designed for electronic groupsets only. This means every Aeroscoop Di2 build that leaves RA Cycles is wired cleanly through the frame, with no external routing to catch wind or accumulate road debris. The electronic-only routing is a deliberate choice that reflects what this bike is designed to be.

34mm Tire Clearance & UDH

Despite its aero road focus, the Aeroscoop accepts tires up to 34mm wide — wide enough for training on varied roads, race day on 28s, or anything in between. The UDH dropout is compatible with current Shimano rear derailleurs and simplifies long-term maintenance and component changes as the ecosystem evolves.

Shimano Di2 — Choosing Your Tier

Shimano Di2 is the electronic shifting benchmark — the system more professional teams have trusted in race conditions than any other, refined across multiple generations to deliver consistent, precise, low-maintenance performance. At RA Cycles, we build the Aeroscoop with three Di2 tiers.

Dura-Ace R9200 Di2 is Shimano's flagship road groupset. The shift quality, weight, and braking performance represent the top of what Shimano produces for road racing. For riders who want the definitive Shimano experience on the Aeroscoop's top-tier carbon platform, Dura-Ace is the conversation to have. Cinelli's own complete build uses this tier for a reason.

Ultegra R8100 Di2 is where the performance-to-investment ratio makes the most sense for most riders. The electronic shifting feel is closely matched to Dura-Ace in real riding conditions, the braking performance is excellent, and the price difference allows you to allocate more toward wheels or other components. This is the tier we recommend most often for the Aeroscoop build.

Shimano 105 R7100 Di2 brings electronic precision to the most accessible price point in the Di2 lineup. The shift quality is genuinely good — a meaningful step up from mechanical shifting at a price that makes Di2 achievable on the Aeroscoop frameset. For riders who want electronic shifting without the full Dura-Ace or Ultegra investment, 105 Di2 is a serious option, not a compromise.

Building Your Aeroscoop at RA Cycles

Your Aeroscoop Shimano Di2 build starts with the frameset and gets configured from there — Di2 tier, wheelset, cassette range, rotor size, saddle. We authorize a hold on your card when you order; no charge is processed until your RA Cycles consultant confirms the build spec and component availability. Every bike goes through full professional assembly before it ships. Lead times vary by configuration; your consultant gives you a realistic window upfront.

If you want to work through the build before committing, reach out directly. We know the Aeroscoop well and can help you choose the Di2 tier and component spec that fits your riding.

Design Benefits

1. Wind-tunnel validated at 205W / 45km/h — airfoil-inspired tube profiles and double-arm seat stays developed through real aerodynamic testing, not styling choices.
2. Shimano Di2 across three tiers — Dura-Ace, Ultegra, or 105 Di2, each delivering the electronic precision and proven reliability that Shimano has refined across decades of professional racing.
3. Columbus T1100 at 950g — high-performance monocoque carbon with a modified layup for the right balance of aero stiffness and ride quality.
4. Columbus integrated cockpit included — Spirit carbon handlebar and carbon seatpost are part of the frameset, spec'd by Cinelli for this platform.
5. T47 threaded BB with ceramics — no press-fit issues, Shimano Hollowtech II compatible via T47 adapters, and ceramic bearings included at the frameset price.

Final Take

The Cinelli Aeroscoop Shimano Di2 Custom Bike is for the rider who wants Cinelli's wind-tunnel-validated road speed built around the electronic drivetrain they already trust. Pick the Di2 tier that fits your investment, and let us build it right. The frame does its job the moment you get up to speed — the drivetrain just needs to stay out of the way, and Di2 has been doing that better than almost anything for years.
