We caught one of Astana’s pro team bikes at the Tour Down Under a couple of weeks back, but around the same time the rest of the team that wasn’t racing there was in Spain for a couple weeks of winter training camp. Several of the riders on the Kazak team were training on the same Gallium Pro we saw in Adelaide, but a couple of the one-day racers and sprinters were training on Argon 18’s aero road Nitrogen Pro. We ran into the team in Calpe and got a closer look at the aero bike, plus had the chance to weigh the all arounder and the E-118 Next time trial machine…
Even with new bikes for 2017, the team carries over sponsor FSA, so the majority of the team were riding these same K-Force carbon bars and carbon-wrapped alloy stems. The riders are still dialing in their fits on the new bikes, which combine extended press-in upper headset cups to provide a range of positions, so the mechanics haven’t cut down the steerer tubes yet.
Like many aero road bikes, the Nitrogen Pro uses a low profile integrated seatpost clamp around its proprietary aero seatpost. But unlike most, it has a unique angled design that makes it easier to access with both mini-tools and standard torque wrenches, ensuring that riders or team mechanics will always be able to tighten it to the proper spec.
