Trek's Domane 4.3 Disc offers unmatched ride quality, comfort, and quickness. This full carbon road machine is graced with race-winning Trek technology like IsoSpeed and an endurance geometry to make it a true ride-all-day rocket. It masters long, epic rides with ease while delivering unrivaled speed and bump compliance. The 4.3 Disc rolls on a precision-shifting Shimano 105 drivetrain with compact cranks for easier climbing. Thru-axles front and rear give you serious corner-carving ability, and the hydraulic brakes deliver impressive stopping power. Plus, you get quality Bontrager components including bar and stem, a carbon post, and tubeless-ready wheels. Uncompromisingly fast, confidently stable, sublimely comfortable, the Domane 4.3 Disc 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 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 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.|
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.

- Great bike
- Can't Ride Enough
I've had my bike for less than a week,(1st road bike in 30 Years) and have truly enjoyed the ride. The bike makes the rough roads a breeze to ride. It is my second Carbon Fiber bike(other is a MTB). Love the STI shifters, and the Disk Brakes grab and stop the bike quickly and affectivly. Looking foward to a lot more riding.
