The Liv Avail Advanced Pro 1 in Aurora Noise is the flagship endurance road bike for riders who want professional-grade technology without the aggressive, back-straining geometry of a pure race bike. For the 2025/2026 season, the Avail Pro series has been redesigned to be lighter and more compliant, featuring a massive jump in tire clearance that blurs the lines between a road bike and a fast gravel machine.
The Aurora Noise finish is a standout feature—a glossy, pearlescent gradient that shifts between deep purples and blues (reminiscent of the Northern Lights), paired with Carbon Smoke sections that reveal the raw composite weave underneath.

Key Performance Factors
Integrated Power Training: Unlike the lower models, the Pro 1 comes factory-fitted with the Giant Power Halo power meter. This allows you to track your wattage and training metrics immediately without any additional hardware.
SL-Grade Performance: While the frame is Advanced-grade, the fork is upgraded to the Advanced SL-Grade, which uses Giant's highest-tier carbon to save weight and provide incredible steering precision.
Carbon D-Fuse Cockpit: This model features the SLR (Carbon) versions of the D-Fuse handlebar and seatpost. They are significantly lighter and offer superior vibration damping compared to the aluminium versions found on the standard Advanced series.
Versatile Gearing: The 46/33 chainring paired with the 10-36 cassette provides a gear ratio that is actually easier than 1:1, making it much easier to stay in the saddle and maintain a high cadence on long, steep climbs.
Aero Integration: The OverDrive Aero system hides all brake hoses internally through the stem and headset. This not only makes the bike faster but also makes it much easier to mount a front handlebar bag for endurance events.
