It's right for you if...

You're beginning to ride faster and further, and you're looking to upgrade to a more performance-orientated road bike that's still comfortable on long rides. You want a wide range of gears for hills, and a reliable drivetrain that won't give up on you – even after thousands of miles.

The tech you get

A lightweight 100 Series Alpha Aluminium frame with hidden mudguard mounts and a stable Endurance Geometry for a confident ride, a road-smoothing IsoSpeed Carbon fork, a full 10-speed Shimano Tiagra drivetrain with a wider range of gearing for long climbs, Bontrager Affinity Tubeless Ready wheels and puncture-resistant Bontrager R1 Hard-Case Lite tyres for extra confidence on rough roads.

The final word

Domane AL 4 is a great choice for riders who want to explore more roads and test their limits. The full 2x10 Shimano Tiagra drivetrain has a wider range of gears than more introductory models, which means that you can take on bigger hills and longer rides with confidence.

favorite_borderWhy you'll love it

  1. This is a bike that makes you want to explore, cover more ground and ride faster – and that's something you can sense as soon as you swing a leg over the top tube
  2. The stable Endurance Geometry is comfortable over long distances, but this is still a quick racing bike
  3.  The unique IsoSpeed Carbon fork, which swoops forward toward the dropouts, absorbs vibrations from the road so your arms won't fatigue as quickly
