Boardman AiR/TT 9.4 Di2

http://ift.tt/1IGowwX

The Boardman AiR/TT 9.4 Di2 is a high-value machine for time trials and triathlon, with a four-position seatpost offering huge fore/aft adjustability and quality parts delivering a luxury ride. Two oversights knock this bike back, though: no Di2 shifting at the cowhorns and an inability to really slam the saddle forward, despite all the adjustability.

  • Highs: Clean, aero frame; good handling manners when in the aerobars; dependable wheels; quality Conti rubber; high-end saddle
  • Lows: No Di2 shifting at the brake levers misses the point of Di2; can't slam saddle right over the BB; head tube angle might feel steep for some

Ride and handling

While decidedly a speed machine, the AiR/TT 9.4 doesn't have drastic geometry, so those coming from road bikes won't feel too out of their element. Riders used to very slack head tubes on tri bikes, however, might find the 73-degree head tube a bit quick in its handling. 

Short (395mm), beefy chainstays make for efficient acceleration and power transfer in general. The bike feels eager to go, responding to pedal inputs without any perceptible waste.

Component selection on the 9.4 Di2 is excellent, with Shimano Ultegra Di2 drivetrain, ISM Adamo saddle and Continental Grand Prix 4000 clinchers

As with any TT/tri bike, how you set up your position has a huge impact on how the bike handles. Here, the standard stem and aerobar make dialing in your fit straightforward. The Vision arm pads combine with the ISM Adamo saddle — a very nice touch as a stock saddle — for a plush, supportive interface.
