Aero? Why compromise on weight?
No need to be flashy. The moment you mount the COMETA and break the wind at the front of the peloton, your true strength will naturally be seen.
▍T1000 and T800 Carbon Frame
The frame uses T1000 and T800 carbon fibre with a full-carbon fork, built to turn your effort into speed whether you are sprinting or cornering fast.
▍Internal Routing, Clean Looks
Say goodbye to clutter and ride the wind. The bike uses internal cable routing with a BOREAS SLR carbon integrated handlebar and a full-carbon seatpost, so no cables are exposed at the front end.
▍Precise Shifting, Total Control
Compatible with multiple drivetrains and paired with hydraulic disc brakes. With a light tap of your fingertip, shifting is precise and on point, so you can focus on every kilometre ahead.

Why Ultegra Di2?
Shimano Ultegra Di2 (R8100 series) sits above 105 in Shimano's road range. It is a 2x12-speed electronic groupset: you shift with buttons, the levers talk to the derailleurs wirelessly, the levers offer reach and free-stroke adjustment, and they also operate the hydraulic disc brakes. With 50/34T chainrings and an 11-36T cassette, the 34x36T low gear helps on Hong Kong's long climbs.
Who Is It For?
- Good fit: riders with road experience who want an aero look and Ultegra Di2. Smaller riders should also take note: the COMETA comes in XXS (seat tube about 454 mm).
- Prefer 105 Di2? The same frame is offered as the HASA COMETA 105 Di2 Road Bike with Carbon Wheelset, with Shimano 105 Di2 and the same frame, cockpit and tyres.
- Want an official weight figure? HASA does not publish a weight for the COMETA. If weight comes first, compare the HASA Deroma 2025 Ultegra DI2 Road Bike with Carbon Wheelset, quoted at about 7.2 kg (size M).
Choosing Between HASA Road Bike Versions
The COMETA Ultegra Di2 and COMETA 105 Di2 share the same T800/T1000 carbon frame, BOREAS SLR integrated bar and Continental Grand Prix 28C tyres. They differ in groupset (Ultegra Di2 vs 105 Di2), chain (CN-M8100-12 vs CN-M7100-12) and wheels. Compared with the Deroma, both use a Press Fit 30 bottom bracket and SAGA integrated headset, but the COMETA frame is T800/T1000 carbon while the Deroma is T1100; per the official geometry, a size M COMETA has 527 mm stack against 548 mm on the Deroma, so the front end sits lower.

FAQ
Is the HASA COMETA a 2026 model?
Yes. HASA lists it as the "2026 COMETA (New)" in its carbon/alloy road bike series, offered in versions including Ultegra Di2 and 105 Di2.
How much does the HASA COMETA weigh?
HASA has not published a complete-bike or frame weight for the COMETA, and weight also varies with size and wheelset. If weight matters to you, please contact us before ordering.
Which wheels come on the HASA COMETA Ultegra Di2?
This is the carbon wheelset version. Jollymap's product information lists Crociera Carbon CS45 carbon wheels, while HASA's official Ultegra Di2 version lists Boreas Stella Eterna 45. Because the two differ, please contact us to confirm the wheelset before ordering.
COMETA Ultegra Di2 or 105 Di2: what changes?
The frame, fork, integrated bar, seatpost and tyres are the same; the groupset and chain differ. This version uses Shimano Ultegra Di2 with a CN-M8100-12 chain; the COMETA 105 Di2 version uses Shimano 105 Di2 with a CN-M7100-12 chain. Both are 2x12-speed with 50/34T and 11-36T.
What colours does the HASA COMETA come in?
Jollymap offers Deep Black, Liquid Silver and Aurora White. HASA's official site lists Liquid Silver, Aurora White and Charcoal Black.
What is the difference between the HASA COMETA and RSX?
The frame specs differ. The COMETA has a T800/T1000 carbon frame, Press Fit 30 bottom bracket and SAGA integrated headset; the RSX has a T800 carbon frame, Press Fit BB-86 bottom bracket and FSA No.55R 1.5" ACR headset. Our HASA RSX Frameset is sold as a frameset without a groupset, for riders who want to build their own bike.
Which COMETA size should I choose?
Use reach and stack as your starting point. The COMETA comes in six sizes from XXS to XL; for example, size M has 383 mm reach and 527 mm stack, and size S has 379 mm reach and 517 mm stack (HASA official geometry).
