Linsey Corbin's Trek Speed Concept.

Corbin sits on her own logo. She rides an ISM Adamo Race with a custom decal.

Corbin's SRAM Red 2012 rear derailleur.

Her front R2C shifter has new internals. The new Red front derailleur doesn't need to be trimmed, it just has two positions. The original R2C tri shifter had intermediate positions to trim the derailleur, but this updates version is designed to match Red 2012 and just has two positions.

Her bikes is painted in the red, white and blue, Corbin has a good chance to be the top American in Ironman Hawaii.

She is racing with two round bottles on her frame.

And of course, a homage to her home state.

Despite getting attention from SRAM's race team mechanics before the race, Corbin sports a chain spotter to ensure her chain doesn't drop to the inside.

Corbin uses the flat profile stem instead of one with a big riser.

The custom paint job on Corbin's bike is outstanding, the colors look really sharp.

Bontrager XXX Tubular tires. 23mm across.

Corbin's bike is ready with a big gear--she has a 55-tooth big ring.

Cow skulls.

Her CycleOps Power Tap power meter is mounted to a bridge between her two aerobar extensions.

A barrel adjuster in line with the front derailleurs helps Corbin and her mechanics dial-in her front shifting. Since the rear derailleur has one built it, that housing isn't spliced with one.

Bontrager's RXXXL Aero brakes. They have an in-line barrel adjuster, like a rear derailleur, to allow the mechanic to adjust brake pad width for different wheels, a major advantage on a bike like the Speed Concept with integrated calipers.
