The Trek Domane 4.5 Disc Road Bike is a new offering from Trek for 2016 featuring a specifically designed fork and frame to accommodate for disc brakes, providing reliable, modulated stopping power whatever the weather conditions, with a minimum weight penalty. These features combined with the IsoSpeed Decoupler and endurance geometry and fit of the Domane ensure blistering speed, incredible race comfort and stability, whether on the punishing pavé of Flanders and Roubaix or riding around your challenging home town terrain.

Trek Domane 4.5 Disc Road Bike 2015

The Trek Domane 4.5 Disc Road Bike is new for 2015 and features Trek's Endurance geometry, a nice balance between an outright race position and a more relaxed one. The Endurance fit, makes it one of the most versatile road bikes on the market. Finished with the Shimano Ultegra 11-spd drivetrain, Shimano R685 Hydraulic Brakes, Bontrager Affinity Comp Tubeless Ready Wheelset, Bontrager R2 Hard-Case Lite Tyres and Bontrager Paradigm 3 saddle the new Domane 4.5 Disc will deliver on all levels.

The Domane 4.5 Disc Road Bike may be new for 2015 but the Domane range has been used for a number of seasons by many professional athletes as well as teams such as Trek Factory Racing and MTN Qhubeka. The range is renowned for being lightweight and tough and stiff yet still offering a comfortable ride. No wonder this in the preferred model for the king of cobbles, Fabian Cancellara.

IsoSpeed technology in the frame allows the seat tube to rotate independently from the top-tube-to-seat stay junction, increasing vertical compliance to twice that of the nearest competitor, without compromising pedalling efficiency. The IsoSpeed fork has a generous ride-tuned sweep with the shape increasing compliance for a smoother ride, and unique dropout placement optimising the wheelbase while an extra curve above the dropout in the swept-leg design creates a smaller angle to the direction of road vibrations. This angle increases fore/aft compliance, better positioning the fork leg to absorb road force rather than transmitting it straight to the rider. The fork lateral stiffness has also been increased maximising both smoothness and control. Both aspects resulting in a bike that you can ride faster for longer.

Power Transfer Construction ensures you get the most out of every pedal stroke by optimising the head tube, down tube, bottom bracket and rear wheel connection. The Domane 4.5 Disc Road Bike 2015 features an E2 head tube which tapers from a 1.5" lower bearing to a 1-1/8" upper bearing, and is wider side to side than front to back. This asymmetric steering system minimises weight while maximising power transfer and keeping the fork stiffer under cornering loads. Resulting in a more powerful and confident ride.

Also featured on the Domane 4.5 Disc is a 3S integrated chain keeper integrated directly into the bike frame. It's an elegant solution that provides flawless gear shifting even on rough roads and under heavy loads. No more standing on the side of the road, covered in grease, unwedging your dropped chain as competitors race by.

The Trek-exclusive carbon BB90 bottom bracket makes the frame lighter, stiffer, and quicker to accelerate. While discreet vanishing mudguard mounts accommodate full-coverage mudguards for added utility and DuoTrap compatibility sees the end of cable ties allowing you to seamlessly integrate a computer sensor into the frame to measure speed, distance, and cadence with no added aerodynamic drag. It works with all the major ANT wireless technology players, including Bontrager, Garmin, PowerTap, and SRM.

The brakes on the Domane 4.5 Disc are post mounted, which is the simplest, most efficient way to mount a brake calliper to your bike. Works great, reduces weight and delivers smooth all-weather stopping to your road bike.
