Packed with specific features for maximum all-road versatility and adventure fun, the Trek Checkpoint ALR 5 Gravel Bike is just as capable cruising tarmac as it is cutting fresh grooves in loose gravel.

Reliable Shimano components and hydraulic disc brakes will perform with you whether the trail leads.

Trek Checkpoint ALR 5 Disc Gravel Bike 2020

The Trek Checkpoint ALR 5 Gravel Bike is engineered specifically for all-road capability, opening up new opportunities to explore previously unridden places. Trek’s exceptional 300 Series Alpha Aluminum is ideally balanced for stiffness and weight, making it strong and durable, even under the stresses of a full adventure load.

The innovative Stranglehold Dropout design lets you adjust the wheelbase and fine-tune the geometry to best suit your preferred ride feel. Furthermore, it’s easy to swap-in a single-speed setup for those who want to simplify the mechanics. When it comes to tackling the steep climbs though, the Shimano 105 50/34 compact chainset and 11-speed, 11-34 cassette, will keep the legs turning and maintain traction over the steepest roads.

The huge tyre clearance gives you optimal flexibility to fit the right treads to suit the terrain, whether that’s a 28c for cruising tarmac or all the way up to a 45c for maximum traction and control over very harsh trails. The bike comes fitted with industry-respected Schwalbe G-One Allround 35 c tyres and the Bontrager rims are tubeless-ready for an extra bit of confidence when rolling over flinty gravel.

Cleverly positioned mounting points for both bottle cages and racking allow for many configuration options when packing your extra accessories and water on multi-day adventures. Customise your kit mounts to position everything you need right where you will need it.


  • Lightweight Trek Alpha 300 Series Aluminium frame
  • Trek Checkpoint carbon disc fork with 12mm thru-axle for added stiffness
  • Intelligent mounting points for racks and bottle cages let you maximise capacity for accessories and water
  • Massive tyre clearance - 28-45c width range
  • Trek Stranglehold Dropout lets you dictate the geometry and ride feel
  • Reliable Shimano 105 components
  • Shimano flat mount hydraulic disc brakes
  • Industry-respected Schwalbe G-One Allround tyres
  • Internal routing protects cables from the additional debris of rough routes and gravel
