Émonda ALR Disc Frame Set

You're building up a disc road bike for club rides or races and you want an advanced aluminium frame with the sleek looks and handling characteristics normally found only in carbon models.

An ultralight 300 Series Alpha Aluminium frame with aerodynamic Kammtail shaped tubes, Invisible Weld Technology for seamless joints and internal cable routing. Includes an Émonda SL carbon fork with a carbon steerer and a headset. Built for flat-mount disc brakes.

Carbon looks and ride quality, aluminium price point. If you thought alloy couldn't contend with carbon in beauty and performance, think again. Émonda ALR Disc frame set is a value-minded ride that's perfectly comfortable taking a far more expensive carbon bike to the line.

The all-new frame is lighter and sleeker than previous ALR models and features aerodynamic Kammtail tubes with even cleaner cable routing
It climbs fast, corners on rails, and descends with confidence
It shares the race geometry of our highest-end carbon Émonda race bikes, and it gives you a ride quality that stands up in every way to far more expensive carbon bikes
Internal cable routing extends the life of your cables and adds to the bike's sleek look

'As good as aluminium road bikes get [...] dialled geometry, smooth welds and an excellent ride feel add up to make the latest aluminium Émonda ALR a great alternative to pricier carbon bikes [...] Trek made a bike that nails all the things that have always made me love aluminium race bikes.'

'Premium performance at a great price [...] it was notable how many admiring comments the Émonda ALR 5 attracted during testing, from cyclists and non-cyclists alike [...] an appealing mix of classic looks and modern tech.'

'Meant for going fast [...] much of the same attributes that have been seen in the pro peloton, but at a much more affordable price [...] it’s responsiveness when I’m out of the saddle, sprinting or cornering, mirrors it’s carbon siblings.'

'The Émonda ALR is one of those bikes that show alloy bikes don't have to be uncomfortable, and for the price, the performance is hard to beat. The new model gets Trek's racier H1.5 geometry as seen on the pros' Gen 7 Trek Madone aero bike.'

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.

An optimised H1.5 race geometry, developed in collaboration with Trek-Segafredo, puts you in the right position for power.

Integrated cable routing cleans up the cockpit and makes the Émonda ALR even faster in the wind.

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.

Trek’s premium-grade aluminium is hydroformed into size-specific tubes that provide the perfect balance of stiffness and weight.

Revolutionary welding technology creates a better connection with each tube junction, increasing strength while using less material.

All-new Flat Mount disc brakes are more elegant, lighter, smaller and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
