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 a comfortable 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 quality Bontrager components including aluminum wheels, bar and stem, a carbon seatpost and a supportive seat. Plus, you get a precision-shifting Shimano 105 drivetrain with a compact crankset for easier climbing and Shimano 105 brakes for total control on the descents. 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 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!
