Trek Checkpoint AL 3 Disc Gravel Bike 2019
The Trek Checkpoint AL 3 Disc Gravel Bike, with a lightweight Trek 200 Series Alpha Aluminium frame, is your go anywhere, do anything buddy. Willing to thrash around on wooded trails, drink in wide open views on winding gravel or brave the elements of a bitter winter commute route, this bike will open up new adventure opportunities. Ride more and see more with the Trek Checkpoint.
With the huge tyre clearance, enabling you to comfortably fit a broad range of widths, from 28 all the way to 45c, there is great scope to customise the ride to suit your terrain, from faster rolling tarmac to rutted and rough stuff.
The build is completed with a Shimano Sora groupset with a compact chainset and 11-32t cassette for spinning up the climbs, confidence-inspiring Bontrager Affinity Tubeless Ready wheels and robust puncture-resistant Bontrager Hard-Case Lite 32c tyres. Tektro mechanical disc brakes will give you the control to tackle the long uneven descents with ease.
