What problem does it solve?

After a season on an entry-level aluminium road bike, many riders want something lighter and faster, but upgrading wheels, cockpit and seatpost one part at a time adds up. The J.Air Fuoco comes with a carbon frame and fork, carbon integrated handlebar, J-AIR carbon aero seatpost and Decaf 50 mm carbon wheels, plus Shimano 105 R7000 shifting, so there is no piecemeal upgrading to do.

Who is it for?

UCI certified and geometric design for long-distance endurance and comfort, this frame is suitable for both general sports and racing. It suits riders who like an aero look and holding speed on the flat, for example along the Tolo Harbour cycle track and Tai Mei Tuk.

If this is your first road bike or you are on a tighter budget, look at the aluminium Java Auriga Disc Road Bike or the Java Siluro 6-18S Disc Road Bike. If you want a carbon frame but do not need carbon wheels, compare the Java Vesuvio 22S Carbon Disc Road Bike.

The frame’s dynamic lines are an expression of the bike’s enhanced aerodynamics and agile handling. With its carefully crafted details, it embodies an aero road bike that unites all its functions and features into a perfect whole. The clear, dynamic form speaks for itself.

Key features

UCI-certified carbon aero frame

The J-AIR Fuoco carbon frame is UCI certified and uses wind tunnel-optimised aero tube profiles. Thru-axles front (12x100 mm) and rear (12x142 mm) with Flat Mount disc mounts.

Carbon integrated handlebar and aero seatpost

Comes with the JAVA Deca carbon aero integrated handlebar (bar and stem in one, 400 mm wide, 90–110 mm stem) and a J-AIR carbon aero seatpost.

Decaf 50 mm carbon wheels

A Decaf 50 mm deep carbon disc wheelset (24H) with 700x25C tyres comes as standard, so there is no need to buy upgrade wheels.

Shimano 105 R7000 shifters and derailleurs (2x11, 22-speed), a Decaf forged CNC crank (50-34T) and an HR50 11-28T cassette. Braking is by Deca cable-actuated hydraulic disc calipers with 160 mm rotors.

FAQ

How is the J.Air Fuoco different from the Fuoco Top / Fuoco 6 on Java's website?

They are different versions. The J.Air Fuoco on this page has Shimano 105 R7000 11-speed shifting, a Decaf crank, Deca cable-actuated hydraulic disc brakes and Decaf 50 mm carbon wheels. The FUOCO Top 105 now on Java's website (Java calls it the 2025 FUOCO 6) uses a full Shimano 105 groupset including crank, cassette, chain and disc brakes, with 700x28C tyres and a stated weight of 8.9 kg.

How much does the Java J.Air Fuoco weigh?

Jollymap's original spec lists 8.7 kg, while the spec icon image on the same page says 9 kg. Weight varies with size, tyres and production batch; for an exact figure, contact us before ordering.

What sizes are available and how do I choose?

Jollymap offers 45, 48, 51 and 54. Java has not published a height chart for this version, so compare the reach and stack in the geometry table above with a bike that fits you, or contact us with your height and inseam.

Does the J.Air Fuoco have hydraulic disc brakes?

Yes, hydraulic calipers operated by cable. The Deca calipers are cable-actuated hydraulic units with 160 mm rotors, paired with mechanical Shimano 105 R7000 levers, so it is not a full hydraulic system.

J.Air Fuoco vs Java Vesuvio 22S: what is the difference?

Both have carbon frames and Shimano 105 R7000 22-speed. The J.Air Fuoco has a UCI-certified aero frame and Decaf 50 mm carbon wheels; the Vesuvio 22S uses a T700 carbon frame and, per its product page, Deca 40 mm aluminium wheels.

Yes. The J-AIR Fuoco frame is UCI certified, and Java's original description says it suits both general sports and racing. Check the equipment rules of each event before entering.
