Product Information

Trek Checkpoint ALR 5 Gravel Bike

The Checkpoint is ready to explore, whatever you've got in mind. Whether that means a continental race across Europe or a local weekend trip out with your family or friends. The 300series Alpha aluminium frame hits the spot of lightweight and rugged durability. Compatible with racks so you can carry luggage around as well as mudguards so you can stay protected in the toughest of conditions. The Checkpoint ALR 5 comes kitted out with Shimano's 11-speed hydraulic disc groupset which is a brilliant option for those who are serious about cycling but aren't looking to be the next world champion. A huge tye clearance of up to 45c means you can get extra traction on challenging surfaces as well as upsize when the ground gets sticky. The Bontrager rims are also tubeless-ready meaning you can greatly reduce the risk of puncturing, meaning more time moving. 

Full Specification



Is this bike for you? 

Unlike the pure roadie who measures watts and weighs out meals, you favour epic all-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 money, including quality, versatility, durability and a ridiculous amount of fun.


What's involved

A 300 Series Alpha Aluminium frame with massive tyre clearance and adjustable Stranglehold dropouts, a carbon fork, 12 mm thru-axles, an 11-speed Shimano 105 drive train and a wide-range 11-34 cassette that's great for climbing. Plus, mudguard and rack mounts, flat-mount hydraulic disc brakes for all-weather stopping power, a Bontrager Elite IsoZone handlebar with foam pads integrated into the tops and 700x40 Bontrager GR1 Comp tyres for added stability and traction.


What to expect

If the amount of adventure you can get per pound spent is a priority for you, you won't do better than Checkpoint ALR 5. Quality parts, a durable alloy frame that keeps the price in check, and a wealth of features like extra tyre clearance and customisation options so you can confidently take on bigger, better adventures.
