The Trek Checkpoint ALR 4 is one of the best, affordable gravel bikes in the market. It travels at a fast speed because of its light, aluminum body frame. The frame also makes the bike ride on any terrain because of its rugged, shock-absorbing carbon fork. It is specifically suited to gravel roads because of the wide, gravel tires. The flat-mounted, hydraulic disc brakes high stopping power when needed.


Lightweight Aluminum frame

The Checkpoint AL 4 is a very fast gravel bike. It can also be used in commuting. This is because of its light, high-performance Alpha aluminum core structure. With this core makeup, it is able to cope with the vibrations and rigors associated with bike riding on gravel grounds. It has integrated  rack mounts, making it easy for carrying of accessories and water bottles

Disc braking system

The flat mount disc brakes system of this gravel bike is topnotch. In comparison to typical road bikes, the hydraulic braking system of the Checkpoint ALR 4 is lighter and way smaller. This gives the bike a great stopping force when required, even in the roughest terrains.  The tires are great for riding on pebble surfaces, giving the rider more body equilibrium and better grip.

Carbonized fork system

This gravel bike comes with a lightweight, carbonized fork set. This enables the rider to go on long bike rides without hand fatigue. In other words, the fork efficiently absorbs all the shocks from the bumps on rough surfaces. This makes the rider comfortable during cycling. The Shimano lever system comes with the “Stranglehold” dropout feature. This allows adjustment of the gears according to the preference of the rider.
