It's right for you if...
Unlike the pure roadie who measures watts and weighs out meals, you favor epic off-road adventures that probably end with a beer and a burrito. But that doesn't mean you'll compromise on performance. You expect to get a lot for your hard-earned dollar, including quality, versatility, durability, and a ridiculous amount of fun.
The tech you get
A sturdy aluminum frame with a progressive geometry that's stable at speed and efficient when you're grinding up a climb, hidden cables that won't interfere with bags, rack and fender mounts and integrated frame bag mounts, a 2x11 Shimano GRX drivetrain with lower gears for grinding up hills or through rough gravel, hydraulic disc brakes for all-condition stopping power, tubeless ready rims, and wide 700x40c gravel tires for added stability and traction.
The final word
If the amount of adventure you can get per dollar spent is a priority for you, you won't do better than Checkpoint ALR 5. Quality parts, a durable alloy frame, and a wealth of features like extra tire clearance and customization options— so you can confidently take on bigger, better adventures.

"An excellent gravel race bike"
"Trek's new Checkpoint SLR 9 eTap is an excellent gravel race bike, built with features and geometry that calm rough surfaces without the handling feeling vague or sluggish. After two months on it, I can say that the bike we named the 2021 VeloNews Bike of the Year has only gotten better."

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
