The Speed Concept 2.5 is Trek's entry-level triathlon/time trial bike. The frame has the Kammtail Virtual Foil aero design employed by the more expensive bikes like the 9.9 that Mat reviewed, only here it's aluminium. The wheelset and gears, however, look like they've been borrowed from a sportive bike, and the tri bars are too high relative to the saddle.
Last Sunday was the first weekend day that felt like spring to me, so I filled a couple of big bottles, put on some shiny new kit and headed out on the Specialized Allez Comp for my first 100-miler of the year. After a few hours on the back roads of Wiltshire and Berkshire, I came home thinking that this is a really neat, value-packed bike that deserves some serious consideration.
