Scott 32″ Aero Gravel Bike Prototype Set For UNBOUND Racing Debut

Scott is set to debut a groundbreaking 32-inch aero gravel bike prototype at the upcoming Unbound gravel race, aiming to demonstrate the performance benefits of larger wheels in off-road racing. The new carbon frame and fork have been developed in-house, eschewing external suspension or complex mechanisms to enhance speed and handling through improved rollover capabilities. Cameron Jones, the reigning Unbound and Lifetime Grand Prix champion, will pilot this innovative machine over the 200-mile course, signalling Scott’s serious commitment to pushing gravel bike design boundaries. The prototype features a distinctive aerodynamic design, blending elements more commonly seen in road and mountain bikes. Its taller front wheel necessitates a longer fork and a steeper downtube angle, resulting in a stretched headtube reminiscent of Scott’s mountain bike geometry. This creates a longer front end with integrated aero shaping, giving the bike a sleek profile akin to Scott’s Foil road model rather than a traditional gravel bike. The extended wheelbase and lowered seatstay angles further contribute to a race-oriented, aero-efficient frame architecture. Technically, the bike is equipped with bespoke 32-inch aero carbon wheels developed in partnership with Industry Nine, although specific details remain under wraps. Jones’ build combines high-end Shimano components, including a mixed groupset of XTR derailleur, Dura-Ace shifters and brakes, and a GRX crankset, alongside ENVE aero bars and Schwalbe RX 32-inch tyres. Fellow Scott athlete Robin Gemperle, known for his ultra-distance racing successes, will also compete on a version of the 32-inch gravel bike, featuring a slightly different aero wheelset and SRAM RED AXS wireless drivetrain. Despite the prototype’s advanced design and race-ready build, Scott has confirmed that these 32-inch gravel bikes are strictly experimental and will not be released commercially. Labelled as “Racing Concept” models, they serve as platforms for real-world testing and athlete feedback rather than production intent. However, the impressive performance claims and high-profile race debut may well influence future gravel bike development, leaving enthusiasts curious about the potential evolution of larger wheel gravel racing machines.
