Product information "Aerfast.3"
The Aerfast.3 Pro is a fast aero race model that has many strengths. A handlebar/stem unit with fully integrated cables, very smooth running and very high rigidity, which is noticeable in direct acceleration when pedalling and can also be felt in the direct steering. In keeping with an aero bike, you sit in a sporty, stretched riding position with a sporty saddle rake. The low weight and balanced sporty properties also make it suitable for marathon cycling. Compared to the Aerfast.3 Comp, it is stiffer and lighter thanks to the even higher quality processing of the carbon fibres.
The Aerfast.3 Comp is a super-fast aero race model, beginner-friendly and offers good value for money. The highlight for this price range is the fully integrated cockpit, which conceals all cables and lines and ensures a contemporary, clean look. The bike's strengths are its smooth ride and very high rigidity, which is noticeable in its direct acceleration and direct steering. In keeping with an aero bike, you sit in a sporty, stretched-out riding position with a sporty saddle rake. The low weight and balanced sporty characteristics also make it suitable for marathon cycling.
