The Aerocomfort 4.0 Triathlon is the definitive solution for transporting Triathlon and Time Trial bikes by air, without removing the saddle, seatpost, pedals, or most handlebars, just the wheels. Its refined exterior geometry follows the shape of modern triathlon frames, keeping bulk to a minimum while ensuring a secure, snug fit inside. At its core, the Frame Defender™️ 2.0 structure locks the frame in place within minutes, while the SkidBoard base absorbs impacts and stabilizes the load from below. Reinforced with 3D-Padding™️, a triple-layer tear-resistant fabric with a high-density foam core, and sealed with the TwistZip™️ GuardLock™️ zipper, the bag delivers uncompromising protection at just 12.30 kg. Two integrated wheel pockets keep wheels safely separated from the frame, and four shock-absorbing SK8Glide™️ wheels make it effortless to manoeuvre on any terrain. The Total Protection Tri Bundle completes this system with the dedicated Triathlon Protection Kit: five triple-layer, 3D-Padding™️ accessories that shield the three areas most exposed to impact, the rear triangle, the handlebar and aero extensions, and the derailleur, applied in seconds for an extra layer of security. The preferred bike travel solution for thousands of triathletes.
