Trek Domane SL 5 Road Bike 2019

For those looking at their first carbon road bike, the Trek Domane SL 5 Road Bike is well equipped and versatile - just as comfortable exploring new rough roads as it is mixing it up in races. The Power Transfer Construction and Trek 500 Series OCLV carbon combine to deliver a stiff, strong bike that delivers more of your effort into speed on the road.

The attention to detail to ensure that comfort is maximised makes this bike ideal for long rides and adventures. The IsoSpeed rear decoupler and Front IsoSpeed provide innovative endurance comfort technology, reducing fatigue-inducing vibrations, increasing compliance and smoothing the road. Furthermore, the Endurance fit and Endurance geometry feature a slightly higher head tube for improved stability and control, without losing that racy edge. Additional tyre clearance will give you the confidence to explore further, and when winter sets in mudguard mounts allow for full protection from road grit and grime.

When it comes to going uphill, the 2x 11-speed Shimano 105 drivetrain with, 11-34 cassette, has plenty of range for even the steepest gradients, and with race-optimised Performance Cable Routing to reduce friction, your gear shifting will stay reliable and consistent whatever the conditions.
