Factor has teased a new aero gravel race bike, with design cues clearly influenced by its radical One aero bike. The bike features a similar wide-splaying fork, which (on the One) is designed to disrupt airflow before it passes over the riders legs. The turbulent air created presents less resistance to the rider behind it. We spotted the new Factor at the Traka gravel event in Girona, Spain.

Simon von Bromley / Our Media The rigid fork crown also sports a similar chin protrusion, essentially starting the manipulation of air sooner than a standard design. We've seen this kind of wide-splaying fork on the One aero road bike. Simon von Bromley / Our Media However, the design is far less pronounced than the Ones, with a slacker angle evident from the handlebar to the fork dropouts. This is likely due to the need for less aggressive handling over rougher gravel terrain. With new 42mm Michelin Power Gravel tyres, there's plenty of clearance left over. Simon von Bromley / Our Media The additional upside to the wide-arcing fork shoulders is enormous visible tyre clearance, with a higher crown granting more clearance for the knobs found on gravel and MTB tyres. This bike, with 2.1in Schwalbe Thunder Burts, still leaves some space. Simon von Bromley / Our Media We first spotted the bike sporting new 42mm Michelin Power Gravel tyres, but its clear it can accommodate much bigger rubber. We also found a bike fitted with new 2.1in (53mm) Schwalbe Race Pro Thunder Burt MTB tyres, which look much closer to the limit. The seatstays appear slim. Simon von Bromley / Our Media The seat tube curves around the rear tyre, much like the prototype Ridley RS2, and the dropped seatstays are notably thin compared to the Ridley or the also-unreleased Canyon Grail CFR. The front wheel features a small number 64, suggesting this is a new deep-section aero wheel from Factor that we might eventually see used on the road, too. Simon von Bromley / Our Media In our experience, Factor has a track record of producing firm bikes for road and gravel use so rather than compliance, which would largely be delivered through wide tyres, we think this is a weight-saving measure. Helpfully, Factor has printed the rear wheel's 64 on the opposite side. Simon von Bromley / Our Media Interestingly, on the bike with Michelin tyres, the Black Inc wheels also look to be new, with the number 64 printed on the front wheel. The aero Factor One road race bike comes with Factor Sixty Two wheels. The new bike doesn't come with many fixtures and fittings A new Sixty Four wheelset debuted on a gravel bike would come as a slight surprise generally, the deepest racing rims are reserved for road racing. ...but there is Monza-style down-tube storage. Simon von Bromley / Our Media Elsewhere, the bike appears not to include storage bag mounts, with tools simply taped to the top tube, but it does feature down-tube storage in a design very similar to the Monza road bike.
