Trek's Madone 4 Series pairs race-level performance and technology with ride-all-day compliance. The light, lean 400-series OCLV carbon frameset boasts a stiff, beefy BB90 bottom bracket for optimal power transfer and a tapered E2 head tube so you can slice through corners with pinpoint precision. The 4 Series also features Trek's DuoTrap technology built into the frame so you can view speed, cadence and more from your ANT+ wireless device (sold separately) all while having the cleanest, most high tech bike around. Shimano's components include a slick-shifting 20-speed Ultegra drivetrain with the perfect gears to spin up the climbs and powerful 105 brakes for complete control on the way back down. This able roadster also sports a sweet line-up of Bontrager's carbon and aluminum components, and a supportive Bontrager saddle, too.
For increased stiffness and improved steering precision, tapered head tubes (see image, on left) and forks pair an oversize lower steerer tube (usually 1 1/2-inch, see image, on right) with a standard diameter upper steerer tube (usually 1 1/8-inch). This combination sheds weight compared to straight 1 1/2-inch systems, and adds stability and stiffness when compared to straight 1 1/8-inch systems. The result is a bike that tracks better through corners while allowing for the use of standard stems.
