Trek Madone 4.5 Compact
Details
From cruising back roads to enjoying all-day epics to getting your feet wet in the racing circuit, Trek's Madone 4.5 does it all. This full-carbon beauty boasts a stiff, light frame that floats up the climbs along with Bontrager's Race Lite oversize carbon fork that provides maximum steering precision. Plus, Bontrager's SSR wheelset cheats the wind, while the Shimano components include a slick-shifting 20-speed drivetrain with the perfect gears to spin up the climbs and powerful dual-pivot 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 plush Bontrager seat, too.
Bontrager's Race Lite Carbon Fork (left) uses a standard 1 1/8-inch steerer diameter at the top in combination with a 1 1/2-inch bottom diameter to increase fork stiffness and strength. This ingenious design also significantly reduces the weight thanks to its oversize bottom, which allows using a hollow aluminum crown bonded to the carbon legs (as opposed to the solid aluminum crowns found on most traditional forks; shown on the right). Trek's oversize E2 head tube adds strength and stiffness. The result is an unbelievably stiff and super-light front end.
