The Checkpoint SL 5 boasts plenty of great features and combines them to make a brilliant all-rounder. It can take on plenty of weeklong adventures and still commute to work on Monday. Trek's exclusive 500 Series OCLV carbon fiber makes up the Checkpoint SL 5's frame, making it very light yet incredibly strong for excellent handling and power delivery. The fit of the Checkpoint is more upright, allowing a wider range of riders -and rider flexibilities- to get comfortable easily. Trek's Checkpoint bicycles received a geometry update since last season. By lengthening the top tube slightly and moving the front wheel out ahead of the rider, the Checkpoint SL 5 is much more stable on rough and technical descents. Called "progressive geometry", this design has been used on mountain bikes for decades to help riders descend with greater confidence. A correspondingly shorter stem and short-reach handlebar produces an identical fit when compared to last year's Checkpoints. A tapered head tube/steerer tube interface adds to the Checkpoint SL 5's handling precision, while a threaded T47 bottom bracket ensures flex-free power delivery with every pedal stroke. The Checkpoint's all-carbon fork is also thru-axle equipped, adding an extra dash of handling precision.
Little details on the Checkpoint SL 5 add up to huge versatility. A 3S chain keeper that prevents dropped chains, roadside delays and greasy fingers. Asymmetrical chainstays offer better tire clearance up to 45mm if you get really adventurous. Internal cable routing for a clean look. A rear IsoSpeed decoupler to soak up fatiguing vibration when thundering over washboard surfaces and rough pavement. Downtube-mounted Carbon Armor defends against rock strikes and front tire "roost". There's plenty of frame mounts and eyelets for racks, fenders, bags and bottle cages.
Shimano's rugged gravel-ready GRX components are found throughout the Checkpoint SL 5. The GRX rear derailleur features a clutch that helps prevent dropped chains on rough and bumpy roads. The new GRX front derailleur's toggle pivot design is much more compact, easier to adjust, and improves clearance for wider tires at the cage's trailing edge. A Shimano GRX crankset features 46/30T chainrings and is matched with an 11-speed 11-34T Shimano HG700 cassette, bringing a very wide gearing range to help tackle challenging terrain. The GRX dual-control levers have a wider range of adjustment for smaller hands, as well as improved lever hood texture. Less effort is needed for each shift, too. The flat-mount Shimano GRX hydraulic disc brakes found on the Checkpoint SL 5 help regulate speed with excellent lever feedback and sheer stopping power, rain or shine. Tubeless-ready alloy Bontrager Paradigm SL wheels are shod with Bontrager's 700x40c tubeless-ready GR1 Team Issue semi-treaded tires, giving the Checkpoint SL 5 excellent grip on road, gravel and hardpan surfaces alike.
Bontrager's Verse Comp saddle, accessory-ready alloy Elite Blendr stem and alloy Elite Gravel short-reach road handlebar completes this epic-ready machine.
Checkpoint's aluminum-framed ALR 5 represents 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 new geometry for riders looking to discover (or rediscover) adventure cycling. The frameset of the Checkpoint ALR for 2022 is slightly different with a slightly longer top tube and correspondingly shorter stem and handlebar reach. Mountain bike designers call this "progressive geometry", allowing better control on gravel-strewn descents. A change to the fork rake ensures the nimble handling of previous Checkpoint bicycles hasn't changed. 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. There's room for tires 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 threaded T47 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. There are even mounts under the top tube for a direct-mount frame bag.
Shimano's proven 11-speed GRX components are built for riding all day in the rough stuff, and are found throughout the Checkpoint ALR 5. Adjustable-reach dual-control levers, a clutch-equipped rear derailleur, toggle-pivot front derailleur, flat-mount disc brakes and a redesigned 46/30T compact crankset are all Shimano GRX components. An 11-34T Shimano cassette boasts a huge gearing range for tackling challenging terrain. Tubeless-ready alloy Bontrager Paradigm wheels are wrapped with Bontrager GR1 Team Issue 700x40c tubeless-ready gravel tires, offering easy acceleration and confident grip in a wide range of surfaces. Shimano GRX hydraulic disc brakes bring effective stopping power to the Checkpoint ALR 5 in all conditions, rain or shine. A Bontrager P3 Verse Comp saddle sits atop an alloy Bontrager seatpost, while an accessory-ready Bontrager Elite Blendr stem and flared alloy Bontrager Elite Gravel road handlebars with a 13 degree flare complete this capable machine.
