The Checkpoint ALR 5 is an aluminium gravel bike built for venturing anywhere.

This bike pairs modern endurance geometry with a carbon fork for road-smoothing comfort, while 50 mm of tyre clearance gives you room for tons of grip. It comes equipped with SRAM Apex XPLR 12-speed shifting, hydraulic disc brakes, Tubeless Ready Bontrager Paradigm wheels and loads of mounts for bags and gear.

You are ready to explore the roads less travelled and want a versatile aluminium bike that is built to tackle it all. You want confident geometry that keeps you comfortable on gravel or rough roads and upgraded components where it matters most, like 12-speed SRAM Apex XPLR shifting.

A 300 Series Alpha Aluminium frame with a full carbon fork, with clearance for up to 50 mm tyres. Upgraded SRAM Apex XPLR 12-speed shifting, hydraulic disc brakes, Bontrager Paradigm wheels with Bontrager Girona Pro Tubeless Ready tyres, plus mounts for loading up with bags, racks and gear.

Want a ride that balances price and performance? The Checkpoint ALR 5 delivers with endurance gravel geometry, upgraded components and an Alpha Aluminium frame that is durable, comfortable and easier on the planet.

Features:

  • The Checkpoint ALR features the same updated endurance geometry as its carbon sibling, giving you comfort and control in the rough stuff.
  • You get road-smoothing comfort from a full carbon fork and clearance for up to 50 mm tyres.
  • It is specified with 12-speed SRAM Apex XPLR shifting that is extra durable and provides plenty of gears for steep climbs and long grinds alike.
  • Lots of mounts on the frame and fork give you places to load up for epic bikepacking adventures or commuting around town.
  • Trek's premium-grade 300 Series Alpha Aluminium is hydroformed into size-specific tubes that provide the perfect balance of stiffness and weight.
  • Wider gravel-specific tyres provide better traction and more stability while riding on gravel or dirt tracks.
  • Flat Mount disc brakes are more elegant, lighter, smaller, and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.
  • Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for road wheels, allowing lower tyre pressure for increased traction and comfort without the threat of pinch flats.
  • Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.
