tri bike test AIRSTREEEM AIR TT PLUS £3,799.00 www.airstreeem.com/en An instantly attractive bike certainly, but would the comparative newcomer’s performance match its handsome looks? E stablished in Salzburg in 2008 by professional cyclist Stefan Probst, Airstreeem is a relative newcomer to the market. But with its own in-house R&D team and insistence on using the very highest quality carbon fibre, their bikes and wheels are seriously impressive-looking. With Svenja Bazlen recently taking one to second spot on the podium at San Juan Ironman 70.3, they clearly ride well too. THE BUILD The Airstreeem Air TT Plus frame is a mean and fast-looking piece of carbon. The carbon fork and headtube blend almost seamlessly to give a wind-cheating nose; the downtube is deep and heavily profiled; and the seat tube hugs the rear wheel. It looks very much a modern cutting-edge speed machine, lacking only integrated brakes in its quest to make the most of your wattage. To come in on budget, we had to say ‘no’ to the wonderful 85mm/1,585g all-carbon tubular flyers that Airstreeem wanted to spec; these would have bumped the price up to £4,499. Instead, the standard spec AL 30 clinchers – still hand-built – are impressively light at 1,500g and, coming in at £599, represent a reasonable spend relative to the build. They do lack that aero wow factor, though, and you’d want to upgrade for a truly race-ready ride. At the heart of the groupset are the excellent light and stiff Rotor 3D cranks, with regular round 53/39t aero Rider chainrings. A 11-28t Shimano Ultegra cassette may be hill-friendly, but will leave “The ride feels bizarrely easy, almost effortless. you quickly settle into a relaxed rhythm” 1 you with a bit of a mid-cassette jump. Shifting is taken care of by the bomb-proof Ultegra mechs and Dura-Ace shifters combination. The Airstreeem’s integrated carbon bars and stem really look the part, but the extensions do lack significant width adjustment; you’d probably end up slightly ruining the clean lines with some bar-tape. Its own-brand saddle ticks the riding-on-the-nose box, while the brake calipers look decent enough. Profile Design brake levers are an appreciated aero touch, too. THE RIDE Although our ex-rugby-playing, wide-shouldered tester could have done with a fraction more lateral adjustment to the extensions, the Airstreeem is further proof that tri bikes can be comfortable. Straight away, it feels familiar and gives you confidence to wind it up to speed and throw it around some corners. The handling on some early tight bends isn’t crit bike-sharp, but it’s certainly above average for a tri bike.

Down on the aerobars and settling into IM pace, there’s a slightly noticeable flex to the extensions, but it’s not off-putting and we did have them at full length. What really strikes you though – despite the abysmal, post-thaw road conditions – is that the ride is butter-smooth. It feels bizarrely easy, almost effortless. You quickly settle into a rhythm and tap out relaxed but rapid kilometres. Shifting is consistently good, but that mid-cassette jump does occasionally burst the Zen-like rhythmic bubble of the ride. Climbing performance is impressive, with no hint of stalling or drag. Although the wheels didn’t especially enhance the ride on the flat, their light weight and build quality make for a great pair of climbing hoops with genuine sparkle and fizz. Heading back down, the Airstreeem descends well. It’s not going to set the mountains on fire, but it’s stable, the braking predictable and it punches well out of the bends.
