Trek made the Checkpoint AL 4 as a step-up from their entry-level AL3 Gravel bike that is designed to take you even further than your road bike could. More adventures, more exploring, more fun, and now with a 10-speed groupset and hydraulic disc brakes you really can go further. And it's true the opportunities with the Checkpoint are endless, it has the capability to carry racks which makes it great for commuting on, it comes with Bontrager's tubeless ready wheelset which helps to significantly lower your chances of getting punctures, making it great for taking on the route less travelled and it the hydraulic disc brakes boost braking reliability and efficiency on any surface or in any condition ... it's hard to find anything not to like about it. The AL 4 comes finished with Shimano's 10-speed groupset that includes a 50/34, compact, groupset so you can roll up the hills and race down them, not being limited to where you can and can't go. Finally, Trek's Alpha Aluminium 200 series frame is backed by a lifetime warranty, so as they say, go break a leg (or not!).
Is this bike for you?
