Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Trek Checkpoint ALR 3 Gravel Bike In Crimson

Season:2025

Brand:Trek

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.

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.

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.

Features:
  • The durable and capable 300 Series Alpha Aluminium frame makes for a fun, stable and responsive ride
