You're building up a disc road bike for club rides or races, and you want an advanced aluminum frame with the sleek looks and handling characteristics normally found only in carbon models.
The tech you get
An ultralight 300 Series Alpha Aluminum 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.
The final word
Carbon looks and ride quality, aluminum price point. If you thought alloy couldn't contend with carbon in beauty and performance, think again. Émonda ALR Disc frameset is a value-minded ride that's perfectly comfortable taking a far more expensive carbon bike to the line.
Why you'll love it
This ultralight alloy frame is designed for racing and packs in super tidy cable routing
It climbs fast, corners hard, and descends with confidence
Kammtail tube shapes help make Émonda ALR even faster than before
It shares the 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 aluminum road bikes get [...] dialed geometry, smooth welds, and an excellent ride feel add up to make the latest aluminum Émonda ALR a great alternative to pricier carbon bikes [...] Trek made a bike that nails all the things that have always made me love aluminum 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."

How tall are you?
To measure your height, stand straight up, 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 inseam?
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 inseam measurement. Your inseam is very important to your final bike size so please measure carefully.
