When Trek decided to improve upon the Equinox TTX, many in the company’s design studios knew they had a big job on their hands. Didn’t the TTX carry Lance Armstrong and Levi Leipheimer to time trial wins in the Tour? Didn’t it prove itself countless times in triathlon victories around the world? How could it be surpassed?
The Speed Concept was born after the Trek aerodynamicists came across an aerofoil concept invented by Wunibald Kamm. Many in the cycling community knew that a long-tail aerodynamic teardrop shape cut through a headwind nicely, but was heavy and frequently tossed around in crosswind situations. Kamm realized when the aerodynamic teardrop shape was cut off near the back, the airstream still followed a clean line with minimal turbulence, almost as if the removed

All the advanced aerodynamic frame design found on the Speed Concept 7.5 is also found on the Speed Concept 7.0 and 7.0 WSD. A TCT frame gives me SRAM’s Apex 10-speed component group rounds out the drivetrain, including a 50/34T compact crank and 11-28 cassette for the easiest hill-climbing gears found on a tri-bike. A fully adjustable aero bar make the Speed Concept 7.0’s an easy fit, and the Bontrager SSR aluminum wheelset makes for a smooth, light ride quality. Internal cable routing, a hidden chainstay mounted rear brake and DuoTrap sensor aperture covers all the details on this groundbreaking machine. The WSD version of the Speed Concept 7.0 has sizes down to XS with a 28.6” standover height and a 46.9cm top tube length to fit a wider ranger of riders and fitting

With an upgraded frame for even better power transfer, the 2011 Lucero keeps all the upgrades from 2010, plus a longer head tube length for a better fit of a wider range of triathletes. Internal cable routing, two bottle mounts and a revised seatpost and seat clamp are just the short list to how the Lucero has improved! Shimano Ultegra crank and front derailleur handle high workloads, while a 10-speed Dura-Ace derailleur handles shifting duties out back. Shimano’s RS-30 wheels spin fast on a day with headwinds, while lightweight Vision clip-on bars run Shimano bar-end

The DA4 is the most affordable of the DA TT/Tri line, and comes out of the same mold as the premier DA1. Ultra High Modulus Advanced carbon fiber combined with the Bayonet 3 fork produces top-notch drag numbers for a new bike split PR. The adjustable alloy stem anchors the Bayonet bar for ease of adjustability. Dura Ace derailleurs are operated with Vision’s new Metron bar-end shifters. TTR3 alloy aero wheels are wrapped with Vittoria’s Zaffiro Pro

It could be argued that this is as good as it gets for bikes to be ridden against the watch. Triathlons or time trials, it makes no difference. You need a bike that is light, comfortable, stiff for efficiency, and -above all- aerodynamic. No, scratch that. It needs to disappear. It all starts with the Wisconsin-made 600-series carbon fiber frame and fork produced with KVF aerodynamic design. Hidden brake calipers, an aperture for a DuoTrap speed/cadence sensor, internal cable routing and even an aero-shaped SC Draft Box for tools and tubes make this a bike that has all the details nailed down. A BB90 bottom bracket holds the SRAM Red 53/39T crankset for maximum power transfer. SRAM’s Red components are found throughout the drivetrain and are shifted with R2C levers at the end of the
