The Trek Emonda ALR 4 Road Bike 2017 is one of the most affordable on the market, comprising of Trek’s ultralight and strong 300 Series Alpha Aluminium frame and paired with Shimano Tiagra 4700 10-speed components that are not just high-performing, but durable, too. You’ll be hard pressed to find anything with this level of spec within this price bracket.

Trek Emonda ALR 4 Road Bike 2017

Using Trek’s ultralight 300 Series Alpha Aluminium, the Trek Emonda ALR 4 Road Bike 2017 blends everything you want out of a road bike into a much more affordable package. Everything from the lightweight, strong frame with Invisible Weld Technology - for a much sleeker look, to the DuoTrap S connectivity for syncing with all your devices, makes this bike a true high-performance option out on the road.

The Emonda ALR 4’s carbon fork enhances the rigidity of the front end, allowing you to sprint out the saddle or spin up the climbs, safe in the knowledge your power transfer is at an optimum level. Adding to the power transfer, Trek have used a Shimano Tiagra, 10-speed groupset to bring together reliable braking and shifting with the ease of maintenance Tiagra is known for.

Shimano Tiagra 4700 10-speed components provides a wide range of gearing to allow you to push yourself to the limit. Whether that be taking on enduring climbs of harsh gradients or laying down the power on the flats, Tiagra will not let you do it. The braking also inspires confidence on the descents, with high-performance delivered whatever the conditions.

Finished with Bontrager R1 Hard-Case Lite 700x25c tyres, Trek have been able to improve grip without costing the rider any rolling resistance and efficiency on the road. The rims combine with this high-performance tyre to create a solid base for power transfer, whilst the ability to go tubeless allows the rider to run even lower pressures which in turn enhances grip and puncture resistance.
