Details

Trek's Domane 4.3 delivers unmatched ride quality, comfort and quickness. This full carbon road machine is graced with race-winning Trek technology like IsoSpeed and endurance geometry to make it a true ride-all-day rocket. It masters long, epic rides with ease while also delivering unrivaled speed and bump compliance. The 4.3 rolls on a precision-shifting Shimano 105 drivetrain with compact cranks for easier climbing. Plus, you get quality Bontrager components including aluminum wheels, bar and stem, a carbon seatpost and a supportive saddle. Uncompromisingly fast, confidently stable, sublimely comfortable, the Domane has it all!

Trek's Domane is a game-changer. It's a high-performance race machine that's also comfortable enough for even your longest rides and roughest roads. Here are some highlights:
The Domane IsoSpeed fork. The Domane E2 front end. The Domane 3S chain-keeper.
The IsoSpeed fork's rake (offset) has been increased to optimize handling and lengthen the wheelbase for greater compliance over even harsh terrain. It's already been proven with wins in races over the toughest cobbles in Europe.
The E2 head tube tapers from 1 1/2 to 1-1/8 inch and is wider side to side than front to back. This minimizes weight, maximizes power transfer and improves cornering. Result: a more powerful and confident ride. The 3S chain-keeper is integrated directly into the frame. It's an elegant solution that prevents the chain coming off on rough roads and under hard shifts. It lets you make any shift you want at any time without worrying.

Trek's BB90.
Trek's Domane features a unique bottom bracket 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 BB90 is machined so that the bearings can be placed directly into the frame saving weight due to fewer parts, ensuring additional pedaling efficiency and simplifying maintenance and repair.

Tapered head tube and fork.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.

    I had a hip replacement in May 2013. Prior to that I was riding a used mountain bike to stay in shape. I purchased a Trek Domane 4.3 about a year ago and I'm blown away by the feel of the bike. Handling is superb and crisp, acceleration is surprising and I can handle long rides with minimal discomfort. I fully expect this bike will last me a lifetime. Great job Trek!

    I was looking to find my first full carbon bike. It had to be comfortable,fast,and reasonably priced. I also needed it to handle rough roads which my old aluminum road bike couldn't. Typically I do longer rides about 30-40 miles per ride 4 days a week. So after a bit of research I heard about the Domane series Trek. It had several qualities to it to ensure a more comfortable ride and less road vibration. ISO Speed decoupler: Separates the seat stem from the from the frame to dampen road vibrations. The more vertically angled top tube keeps the rider more upright. And wide grip handlebars are excellent for good and comfortable hand positions. All this makes for a versatile bike that can serve as a commuter, touring,cobblestone/gravel,and road racer.

      Comments:

      I ride about 230 Km's per week. At 67years old I find that distance is fairly easy to do. The bike is comfortable and I can maintain a good speed on the flat and manage the hilly parts of the rides quite well. This is the first road bike I've owned and my weekly average distance has jumped by about 80 Km's. The wind here in Tasmania can be a problem but again the bike seems to help overcome this without too much of a problem. The only negative is, I can't get out on the bike enough

      I recently sold my C-Dale Super Six 4(2012), incredible bike. Sold it because baby on the way. Recently bought a Trek Domane 4.3c and I couldn't be happier. Not quiet as fast as my old bike but the comfort level has gone up 100%. My back and hands being more relaxed and upright has improved my longer rides. I noticed this because before I got this bike I was constantly having to change my hand position because I was uncomfortable. Not anymore with the Trek. This was the perfect bike for me. Trek compact frames has changed my riding experience for ever. Perfectly suited for my riding style, Thx again Trek!!!!! P.S. I am 44 years old and 5'10 inches tall.

      I've owned the Domane 4.3 C for 10 weeks now and have logged just over 700 miles so far this summer. To be fair this is my first carbon frame bike, but I am utterly blown away. My hours in the saddle and miles have gone up dramatically over my the amount I used to ride on an aluminum bike.

          I got this bike with getting in shape as my main goal since I just turned 60. Started riding in November '13 and out of shape. I'm up to 26 miles in a day and adding distance every week. This feature that impresses me the most in how comfortable this bike is compared to the others I tried. The Domane frame really is smooth and is, at the same time, fast. It handles very well IMHO. I have the 4.3C. For me, this is the Goldilocks of bikes... Not too radical but not too upright. I'm glad I chose this bike. I test rode Scott, Fuji, and others. Did I mention it rides stable, quick, and is very smooth? I will doing Centuries very soon!
