This Surprised Me… Avenger Shuttle SL Review
Underdogs Cycling
December 12, 2025
In this video, I review the Avenger Shuttle SL — a surprisingly refined aero/all-rounder frameset with great design details, competitive weight, titanium hardware, and excellent value for the price.
I walk through:
• Aesthetics & design
• Handlebar and cockpit details
• Frame shaping (downtube, top tube, seatstays, chainstays)
• Seatpost design & practicality
• Geometry similarities to Factor O2 VAM and Cannondale SuperSix EVO
• Pricing differences between SL and non-SL versions
• My real ride impressions after testing the frameset
