Why do we love the Trek Domane 4.5 C ?

The Trek Domane 4.5 C is available on 0% finance with only 10% deposit. The Trek 4.5 C 2013 IsoSpeed decoupler gives you an incredibly smooth ride Power Transfer Construction puts all your power to the road.

Domane 4 Series blows past any other carbon endurance race bike in its class, with IsoSpeed for comfort, Domane geometry for stability, and Power Transfer Construction for speed.


E2 Head Tube and Fork: E2 tapers from a 1.5" lower to a 1-1/8" upper, placing more material where it matters most for the stiffness of a full 1.5" system without the added weight.

10 Speed: The standard in race performance gearing.

BB90: BB90 is the widest bottom bracket available on a road bike. This Trek-exclusive carbon BB makes the frame lighter, stiffer, and quicker to accelerate.

Direct-Mount Front Derailleur: Provides accurate gear shifting in a lightweight, minimal package.

Crank: Compact: Two front chainrings with shorter gearing, for the best combination of climbing ability and flat-terrain speed.

DuoTrap Compatible: DuoTrap seamlessly integrates the computer sensor into the frame to measure speed, distance, and cadence with no added aerodynamic drag.

3S Integrated Chain Keeper: Our 3S chain keeper is integrated directly into the bike frame. It's an elegant solution that provides flawless gear shifting even on rough roads and under heavy loads.

400 Series OCLV: Over two decades ago, Trek engineers developed our Optimum Compaction, Low Void carbon manufacturing process, enabling us to produce carbon bikes with consistency and quality previously thought impossible. It was an industry breakthrough… and to this day, Trek OCLV carbon frames are the best, most consistent you can buy.

Power Transfer Construction: Our Power Transfer Construction puts more power to the road by optimising the E2 > down tube > BB90 > rear wheel connection.

IsoSpeed Decoupler: A technological revolution. IsoSpeed isolates the seat tube from the rest of the frameset, doubling compliance and comfort with zero performance drawbacks.

IsoSpeed Fork: It's a one-two punch: generous ride-tuned sweep and shape increases compliance for greater comfort, and unique dropout placement optimises the wheelbase.

Endurance Fit: As befits Domane, the world’s most comfortable performance racing bike, we’ve developed the world’s most comfortable racing geometry. Still racy, but with a slightly higher head tube.

Endurance Geometry: Performance. Stability. Victory. Domane endurance geometry is a triple threat, maximising control, handling, and responsiveness through perfectly tuned rider weight bias.

Vanishing Mudguard Mounts: Discreet mounts accommodate full-coverage mudguards for added utility
