The ultimate featherweight
The Émonda ALR was built with our best and lightest 300 Series Alpha Aluminium and a gram-trimming design to keep things light, fast and fun.
Race-ready geometry
An optimised H1.5 race geometry, developed in collaboration with Trek-Segafredo, puts you in the right position for power.
Refined integration
Integrated cable routing cleans up the cockpit and makes the Émonda ALR even faster in the wind.
Faster than ever
The Émonda ALR's new Kammtail aero tube shaping keeps things light and fast wherever you ride – whether you're powering up climbs or racing across flats.
Shimano 105 Di2
With a shared Di2 platform inherited from Dura-Ace and Ultegra, sophisticated ergonomics, Shimano 105-optimised gear combinations and an exceptional hydraulic disc brake system, Shimano 105 Di2 R7100 marks a new era of affordable, 12-speed electronic performance. You can set up the drivetrain just the way you like it via Shimano’s user-friendly E-Tube app.
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.
300 Series Alpha Aluminium
Trek’s premium-grade aluminium is hydroformed into size-specific tubes that provide the perfect balance of stiffness and weight.
