Simon Clarke finished seventh in the just-concluded Australian UCI National Road Championship. The vehicle he used for this race appeared to be a new Factor Ostro Vam, a new and more aerodynamic frame that was used in the 185The 6km race gave him enough of an advantage.
Members of the PATEO team also posted the new Factor Ostro Vam on the Weight Weenies forum, where the details of the Factor Ostro Vam can be seen in detail.
Either way, it's clear that Factor is looking to improve the aerodynamic efficiency of the frame. Factor moved the Ostro's head tube inwards to make the front more prominent, but also narrower and sharper. We've also seen this design on the Specialized Tarmac SL8, which we call the "Speed Sniffer";There's also Cannondale's SystemSix and Pinarello's Dogma, which is nothing new, but it's the first time I've seen it on Factor.
As expected, the new Ostro has a much thinner chainstay than the current one, and then the fork legs are also wider than the current Ostro, a design that is often used to reduce drag in this area, so what we see on both time trials and track bikes is very exaggerated.
Looking at the seatpost, it's narrower and more shapely than the current Ostro Vam. The position where the riser connects with the rear wheels is also inline, presumably to reduce the disturbance of airflow in this position. Another change is that the top tube of the frame is tapered from front to back, reducing the overall weight of the frame.
It's unclear from these angles whether the **Ostro Vam features the "Twin Vane Evo" downtube found on the Factor One aero road bike. But considering weight is also very important for Factor's all-around road bikes, it seems unlikely.
In addition, Simon Clark's Ostro Vam is fitted with a pair of new Black Inc wheels, with a 48 front and 58 rear settings, which are claimed to weigh just over 1,300 grams.
