It's right for you if...
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
A lightweight 300 Series Alpha Aluminum frame with shaped tubes, Invisible Weld Technology for seamless joints, 12mm thru axles, and internal cable routing. Includes an Émonda SL carbon fork with a carbon steerer and internal brake routing, plus a headset. Built for BB86.5 bottom bracket and 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 is a value-minded ride that's perfectly comfortable taking a far more expensive carbon bike to the line.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
