The Trek Émonda ALR 4 is a lightweight aluminium road bike at an incredible price. Just like every model in the Émonda line-up, Émonda ALR 4 is built to be the lightest in its class and backed by our lifetime warranty. It’s perfect for new riders and anyone looking to take on faster rides with a race-worthy bike from our lightest road bike family.


Product Description

It’s right for you if…

You’re a value-minded rider looking for a lightweight racing bike, a whole lot of performance for your money and a quality ride that you won’t immediately outgrow.

The tech you get

Émonda ALR 4 is more than the sum of its parts. Yes, it has a full Shimano Tiagra groupset, 20 speeds, a carbon fork and a lightweight 300 Series Alpha Aluminium frame – but its real genius is in its handling and ride quality.

The final word

Émonda ALR 4 is the most affordable Émonda in the family, but it handles like a far more expensive bike and has the looks to match. It’s an extremely capable racing bike at a great price.

Why we love the Trek Émonda ALR 4

  1. It gives riders room to grow, with dependable components and lightweight performance at a great price
  2.  It handles like a far more expensive bike – it climbs fast, corners on rails, descends with confidence
  3. No one likes ugly welds: Invisible Weld Technology for seamless looks and lighter weight
  4. It shares the geometry of our highest-end carbon Émonda racing bikes, and it gives you a ride quality that stands up in every way to far more expensive carbon bikes
