Checkpoint's aluminum-framed ALR bikes represent Trek's commitment to riders looking for freedom and adventure, but who also look for value.
The Checkpoint ALR 5 combines rugged construction, a responsive feel, versatile design and a fun-loving geometry for riders looking to discover (or rediscover) adventure cycling. An upright fit allows a wider range of riders -and rider flexibilities- to get comfortable. The 300 Series Alpha aluminum frame features tapered and butted tubes created by hydroforming, keeping weight low while adding plenty of strength. The adjustable Stranglehold rear thru-axle allows the rider to change the wheelbase up to 15mm, adding stability and tire clearance. How much clearance? Up to 45mm (!), depending on rim width. A tapered head tube/steerer tube interface also adds handling precision while traversing rough surfaces. There's more strength to be found at the press-fit BB86.5 bottom bracket that all but eliminates power-robbing flex at the crankset. A 3S chain keeper, Control Freak internal cable routing, and accessory mounts from stem to stern demonstrate how much this bike is ready for expeditions across town or across the state.
Shimano's latest 11-speed GRX components are found throughout the Checkpoint ALR 5. GRX dual-control levers feature comfortable lever hoods and an adjustable lever reach for shorter hands. A 46/30T Shimano GRX crankset is matched with an 11-34T Shimano 105 cassette, boasting a very wide gearing range for tackling challenging terrain.
