Triathletes, meet Jamis Bikes and their new Xenith T1 and T2. Sure, Jamis has been making TT bikes for years and they’ve picked up a good following with roadies, thanks in part to their sponsorship of the Colavita/Sutter Home Pro Cycling Team. While their road bikes have always been top notch, the New Jersey based bike builder never had a serious, top-of-the-line triathlon bike – until now.

Greg Webber and the rest of the Jamis crew knew they built a fast bike, but they wanted to know just how fast it could be. So, they packed up a Xenith complete bike and headed to the San Diego Low Speed Wind Tunnel last week. Triathlete Magazine met up with the guys from Jamis at the wind tunnel and you could say we were more than a little impressed.

We were sworn to secrecy over the exact results of from the wind tunnel (we’ll let Jamis show off the details at Interbike), but we can tell you that it’s fast – really fast.

How fast?

Let’s just say when you compare drag numbers between the Xenith and some of the other tunnel-proven TT bikes, the results are, well, jaw-dropping.

The culprit?

Jamis’ state of the art Super Aero shrouded front fork allow the front brake to be literally hidden from all air flow, creating a significant reduction in drag. But, hiding the front brake wasn’t enough, so the engineers tucked the rear brake under the chainstay, keeping the airflow as clean as possible.

The rest of the specs on the bike are what you would expect from an elite-level tri bike: Monocoque frame, internal cable routing, aero tubing, horizontal dropouts, and a dual position aero seatpost, allowing for athletes to ride at 75 or 78 degrees.

Buyer’s will have the option of the Xenith T1 or T2, with the T2 being the cream of the crop, in terms of accessories. The T2 (which will retail for $6,300) comes complete with a Zipp 808 wheelset, Dura-Ace derailleurs, FSA Hollow Carbon TT crank (with ceramic bearings), Easton Attack TT bar and Vision Tech aero brake levers.

The Xenith will be available in four sizes (S, M, M/L, XL), with the medium/large model (56-58cm) tipping the scales at 16.75 pounds.
