Checkpoint ALR 3 is the best value gravel bike in the line-up. Kitted out with a 300 Series Alpha Aluminium frame, the Checkpoint ALR 3 is just as responsive on chunky gravel roads as it is smooth on the tarmac. Tubeless-ready wheels help fight punctures in the rough while a 2x9-speed Shimano group set and mechanical disc brakes balance budget with reliability.

Highlights:
- This bike is exceedingly versatile and suited to a wide variety of riding styles, including gravel rides, bikepacking and daily commutes.
- It's progressive geometry is quick and nimble yet keeps you stable and in control on fast, choppy descents.
- Integrated frame bag mounts and rack and mudguard mounts make it easy to carry gear and water
- Massive tyre clearance means you can use tyres from 28c all the way up to 45c for extra traction and stability in any condition.
- Super-advanced aluminium frame: Trek's premium-grade 300-series Alpha Aluminium is hydroformed into size-specific tubes that provide the perfect balance of stiffness and weight.
- Powerful mechanical disc brakes make stopping in all conditions easy.



It's right for you if...
You want to make the jump into the wide world of gravel, exploration and even daily commutes that wander off the beaten track ??" and you don't want to break the bank leaping in.

The tech you get
A responsive 300 Series Alpha Aluminium frame, hidden cables that won't interfere with bags, integrated rack, mudguard and frame bag mounts, a 2x9 Shimano Sora drivetrain for smooth shifting on punchy climbs and variable terrain, mechanical disc brakes for ease of stopping quick in all conditions, tubeless-ready rims and wide Bontrager Girona Pro 700x42c gravel tyres for added comfort and traction.

Details:
- High performance: Highly engineered 300 Series Alpha Aluminium frame - Trek's premium aluminium, formed into sophisticated tube shapes for maximum strength and minimum weight. Revolutionary Invisible Weld Technology offers a better connection at each tube junction, increasing strength while using less material. The results are smooth and flawless seams, stronger bonds between the frame's tubes, sparkling aesthetics, and decreased frame weight.

- Tapered headtube: The fork tapers from a 1.5" lower bearing to a 1 1/8" upper bearing. The larger-diameter lower bearing keeps the fork stiffer under cornering loads and distributes forces more evenly, increasing the life of the bearings. Result: a more confident and durable ride.

- Flat Mount Brakes: more elegant, lighter, smaller and cleaner than traditional disc brakes.

- 3S integrated chain keeper is integrated directly into the bike frame. It's an elegant solution that provides flawless gear shifting even on rough roads and under heavy loads. No more standing on the side of the road, covered in grease, unwedging your dropped chain as competitors race by.

- Blendr Integration: Blendr seamlessly mounts Bontrager Trip computers, Bontrager Ion lights and Garmin computers directly to the handlebars, keeping everything zip tie-free and in its place.

- Mudguard and pannier rack compatible: Mudguard mounts allow for full-coverage mudguards so you can ride comfortably in less-than-ideal conditions. Rack mounts enable Checkpoint ALR to become your favourite commuter or touring bike.
