It's right for you if...
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.
The tech you get
A lightweight 300 Series Alpha Aluminium frame with shaped tubes, Invisible Weld Technology for seamless joints, 12 mm 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, aluminium 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.
