The All-New HASA COMETA Carbon Aero Road Bike
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.
(Available options: SHIMANO 105 Di2 Electronic / Ultegra Di2 Electronic)
【 Key Specifications 】
- Frame Material: T1000 / T800 Carbon Fibre
- Tyres: CONTINENTAL Grand Prix 700×28C (TPU inner tube)
- Colours (Jollymap): Deep Black / Liquid Silver / Aurora White

Why 105 Di2?
Shimano 105 Di2 (R7100 series) is a 2x12-speed electronic groupset: you shift with buttons, the levers talk to the derailleurs wirelessly, button functions can be customised in Shimano's E-TUBE app, and the levers 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 who want an aero look, electronic shifting and carbon wheels in one package. Smaller riders should also take note: the COMETA comes in XXS (seat tube about 454 mm).
- Want Ultegra Di2? The same frame is offered as the HASA COMETA Ultegra Di2 Road Bike with Carbon Wheelset, with Shimano Ultegra 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 105 DI2 Road Bike with Carbon Wheelset, also with 105 Di2 and quoted at about 7.3 kg (size M).
Choosing Between HASA Road Bike Versions
The COMETA 105 Di2 and COMETA Ultegra Di2 share the same T800/T1000 carbon frame, BOREAS SLR integrated bar and Continental Grand Prix 28C tyres. They differ in groupset (105 Di2 vs Ultegra Di2), chain (CN-M7100-12 vs CN-M8100-12) 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.
