Heather Jackson’s Cannondale Slice features mechanical Shimano Dura Ace components, which offer an excellent balance of high-performance shifting while maintaining the reliability necessary to endure the rigors of Kona.

Although the bike is pictured with a standard water bottle in the between-the-arms location, Heather will reportedly be using the Speedfil A2 system come race day.

Jackson’s Shimano Dura Ace drivetrain has been outfitted with the best that CeramicSpeed has to offer. The company’s ceramic bearings are used in the derailleur pulleys and bottom bracket to minimize every last bit of friction. A Shimano Dura Ace 11-28 cassette is used on the rear, likely to provide a wide range of gear options and while allowing Jackson to keep the chain on the large chain ring as much as possible.

The Pro Missile EVO carbon fiber aerobar setup supports Jackson in an optimized aerodynamic position, while the low profile aero shapes of the base bar help to shave every last bit of time off the bike split.

Jackson has chosen a TriRig OMEGA-X front brake caliper, which has an aerodynamic shape and a low profile to minimize drag in one of the most important areas of the bike for aero optimization.

The Shimano Dura Ace crank is outfitted with the Pioneer Power Meter, which measures the left and right leg independently for optimal power analysis. A CeramicSpeed UFO Racing Chain features a special treatment that reportedly save 2-5 watts over the course of approximately 200 miles, plenty more than the 112 miles that Jackson will need it for come race day.

Knight Composites 65/95 carbon clinchers built on Chris King hubs with ceramic bearings will help Jackson slice through the wind on race day. These wheels reportedly perform well at a wide range of yaw angles, something that might prove to be an advantage in the wind-swept lava fields of the Kona course.

Jackson opts for the split nose design of the ISM saddle, which helps her maintain an efficient aerodynamic position even over the course of an Ironman.
