The TT Bike to Beat the Clock

Aero wind-defying technology twinned with an integrated front end delivers a true clock-beater! This thing is fast.

The Aeolus

A wind tunnel refined frame with fully enclosed front aero integrated brakes, an adjustable seatpost offering 74°–78° seating angles, and Aspire's own multi-adjustable cockpit, means this time trial bike is made purely for speed.

A Time Trialist's Dream Bike

This bike is a favourite amongst Triathletes and Time Trialists. We've worked on both the geometry and front end set up to deliver something that is truly fast but also a bike you can live with. Our recommended set-up comes with a disc wheel, deep section front wheel and sleek electronic shifting to remove excess cabling and drag. We can work with you to create the perfect combination for you to smash that PB!


Everything you need to know about the Aeolus. Detailed information about the available sizes and specifications of this frame can be found in the Aeolus Geometry Factsheet.

Aero Optimized Head Tube

To reduce drag, the Aeolus’s cockpit and fork are seamlessly integrated into the frame’s front triangle, so rider and bike slice through the wind.

High Modulus T800 Carbon Fibre

The highest quality materials are used for Aspire carbon frames. Referred to as high modulus carbon fibre, they offer the best combination of strength and elasticity, providing maximum lateral stiffness for best power transfer and a high level of comfort. The result, a light, stiff, comfortable time trial bike.

Full Carbon Aero Fork

Using a full carbon fork leads to a vastly improved riding experience due to their stiff, lightweight properties, resulting in knife-sharp steering precision, effortless climbing and maximum lateral stiffness.

Internal Cable Routing

Both braking and shifting cables are routed internally for cleaner air flow, resulting in improved aerodynamics.

Di2 Ready

Electronic shifting components provide incredibly fast and reliable gear changes with minimum maintenance – a real asset across all disciplines of riding and racing. The Aeolus frame can integrate batteries and electric cables as well as conventional wires.

Frame-specific Carbon Aero Seatpost

Specifically designed and manufactured to complement the Aeolus frame, the Aspire adjustable AR seatpost offers 74–78° seating angles, whilst filtering out annoying and energy-sapping road buzz, without adding weight or losing stability. Aero doesn’t have to mean uncomfortable.

Aero Integrated Brakes

Expert engineers have developed a brake system for the Aeolus that is perfectly hidden from headwind. Fully enclosed at the front of the forks and behind the bottom bracket shell at the rear, further enhancing the wind-cheating aerodynamics of the bike.
