The Trek Madone 4.5 is the entry level road bike in the Madone series and the only bike in the group along with the Madone 4.7 that has a TCT carbon frame instead of the standard OCLV based frame. Shimano 105 series parts are used for the drivetrain which includes the shifters, derailleurs, crank and cassette as well as breaks, and, Bontrager components have been included as well which make up the saddle, seat post, handlebars, stem, headset and brakeset. Double and triple chain versions are available although the bike can not be purchased with the 'Pro fit' shorter head tube like others in the series, only 'Performance fit' is offered. The overall weight is extremely light and even lighter than some bikes that cost more, including the wheels and tires which are also made by Bontrager. Although the frame is made from a slightly less expensive material, the TCT carbon frame is strong enough to support medium to heavy riders who enjoy the odd road race yet aren't competing on the pro-level.
