The Specialized Amira S-Works SL4 of American Olympic triathlete Gwen Jorgensen.

The bikes of draft-legal Olympic triathlon superstars look quite a bit different than those of their non-drafting counterparts.

There is no doubt who this bike belongs to and what country she represents.

Specialized has supplied Jorgensen with their Romin Evo Team saddle, complete with carbon fiber rails, part of the company’s Body Geometry lineup.

This bike is equipped with the new CycleOps PowerTap G3 hub, which transmits power and speed data wirelessly to a stem-mounted head unit.

Shimano’s Dura Ace 7900 groupset provides reliable performance with crisp shifting and powerful braking.

The CycleOps Joule 2.0 head unit provides a wealth of data to Jorgensen while on the bike, with the ability to download telemetry post-ride for further analysis.

Hed Jet clincher wheels allow for breakaway potential, though they are equally at home riding in the pack. As an added bonus, the metal brake track allows for maximum stopping power with standard brake pads.

Sometimes even world-class professional athlete use equipment that might surprise, and these Shimano 105 pedals are no exception. The bottom line, these pedals get the job done.

The SL4 represents the pinnacle of what Specialized have been able to do with carbon in terms of light weight and stiffness.

Rolling on Specialized S-Works clinchers has another, sometimes overlooked benefit: extra-long valve tubes remove the need to deal with unreliable valve-extenders.

Attention to detail is everything. Cables are cleanly routed from the handlebar, there aren’t any excess spacers under or over the stem, and even the zip ties used for the computer mount line up cleanly.

The oversized tubes used on the front end of the S-Wowrks Amira stiffen the front end and make this bike handle like it’s on rails, very important in the lightning fast world of technical ITU-style bike courses.

A small bit of electrical tape can go a long way toward making sure this globe-trotting bike’s saddle is always adjusted back to the proper height.

The mechanical Shimano Dura Ace 7900 rear derailleur takes care of the majority of shifting duties come race day.

The shift cable housing elegantly exits the Amira SL4 frame as it cleanly loops back to the rear derailleur.

The rear cassette features tightly-spaced gears, allowing Jorgensen to always find the cadence she’s the most comfortable with.

The seat-stays of the SL4 take a wide stance even toward the top of the junction with the seat tube, helping to stiffen the bike and make sure every watt gets transferred to the rear wheel.

The Shimano Dura Ace 7900 brake calipers are widely regarded as some of the best on the market for their ease of adjustment and reliable braking power.
