The DA has available a set of one-piece stems in high-rise, medium-rise and flat aspects. Obviously, flat (low) was used here.

Note the lack of tape on the bars.the tire was a Crono CS, the very light, very fast, but less durable choice than Vittoria's CX.

This is the seat post a UCI rule-encumbered rider is obliged to use. The standard seat post is pitched forward, for use in tri. At the terminus of this gallery you'll see a link to Andreas Böcherer's Felt DA. It's got that tri-specific seat post you'll probably want.

Both the male and female gold medal winner used a non-round set of rings. In this case, it's a Rotor Q-Ring set up, 54x42.

The groupkit was SRAM Red, the new 2012 version, with a few minor exceptions. Note how short the chain stay, to get the tire as close as possible to the seat tube.

Our tech editor Greg Kopecky just wrote about valve extenders. The choice here is to protrude the entire presta valve out of the rim, to make sure you can open and close the valve.

Kristin and her husband, mechanic Joe Savola, designed a chain catcher marketed by K-Edge. It's used here, but SRAM's own chain catcher will do the job nicely.

Felt had a lot of bikes in the Olympics, including on the track, and some had custom paint jobs like this.
