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.

Cockpit

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.See More

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.

Handlebars

The final word
When you want to start exploring the road less travelled, reach for the Checkpoint ALR 3. This budget-minded gravel bike gives you room to grow from rugged commutes to gravel grinds with economical components and a comfortable, capable frame that's built to take you on every adventure.

Stems

How tall are you?
To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

Grips & Bar-Tape

What is your inside leg?
How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
