Please select options


Hungry for more velocity? Trek's Madone 5.5 delivers a delicious ride with speed to spare. Speed comes courtesy of Trek's TCT carbon frame, which boasts ingenious technology that makes every ride better. The 90mm-wide bottom bracket gives you a stiff, efficient pedaling platform, the integrated headset and BB cups press directly into the frame to save weight and the seatmast saves even more weight, and adds compliance for long-ride comfort. The Race X Lite Carbon fork boasts a tapered steerer for precise steering and awesome efficiency with minimal weight. You also get Bontrager's Race Lite wheels that let you carve corners and fly up climbs and you'll love the gorgeous looks, and quick, positive-shifting action of SRAM's Force group.

Bontrager Race Lite Carbon fork

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.

Trek's BB90.
Trek's Madone features a unique bottom bracket (image, right) that's 90mm wide (traditional ones are 68mm wide). This wide bottom bracket lets Trek build the frame with larger tubes for increased power transfer. Plus, the 90mm bottom bracket is machined so that the bearings can be placed directly into the frame (image) saving weight (due to fewer parts, below), ensuring additional pedaling efficiency and simplifying maintenance and repair.

Instead of a conventional seatpost, Trek's Madone boasts a seatmast (image). Compared to traditional seatposts (image, left) and also modern integrated seatmasts, this engineering masterpiece boosts strength and pedaling efficiency, saves weight, increases compliance a whopping 39% (for maximum comfort), and offers all the adjustability you'll ever need (no cutting required). It lets your Trek fit in a UPS-compatible box for shipping, too!
Madone seatmast height range
This chart shows the maximum seat height for each Madone frame size. To determine which is right for you, we recommend measuring the seat height on your current bicycle.

Trek's fit system lets you get the bike that fits you perfectly.
Whether you're looking for the most aero riding position, to sit as upright as possible, or anywhere in between, with Trek's H1, H2 and H3 fits, there's a Madone that's perfect for you.

H1 (see yellow dots on illustration) is Trek's most aggressive, most aero fit, with the lowest handlebar-position options.
H2 (orange dots) is the right fit for most riders. It sports the same handling as the H1 fit, with a slightly taller head tube that puts the handlebars higher.
H3 (red dots) boasts an even taller head tube and higher bars than H2 and a small handling adjustment for even more stability.

    I bought the 2011 model just after the new 2012 models were introduced and saved a significant amount of money. I think the only difference is the new frame on the 2012 models can be fitted with the Ultegra electronic components and the paint color was changed. Although I don't race and ride exclusively for exercise and recreation, the Madone 5.5 is extremely fast and climbs well. The H2 geometry provides a more comfortable riding position and enables me to spend longer hours in the saddle. My 56 cm bike with pedals weighs 1-2oz over 16lbs. The bike is light, responsive and handles great. I also like the SRAM Force components, shifting is smooth and efficient. This is my first road bike, so I did a lot of research prior to purchasing and concluded that the Madone 5.5 offered the best bang the buck in an above average price range. Based on past bike buying and selling experience, I decided to go directly with what I thought would be my first and last road bike purchase. I believe it's more expensive in the long run to buy less bike now when you intend on upgading later. Unless your goal is to do some serious racing, you will never outgrow this bike. It's a great performer and fun to ride! The Trek Stores in the Pittsburgh area are terrific, especially at Robinson Town Center. A good bike shop will help you select the right bike that will satisfy your riding goals and needs. Hope this helps!
