Trek's Checkpoint SL 6 gets a few upgrades from the previous season.

Technology mixed with decades of engineering experience at Trek has led us to awesome machines like this. Trek's 500 Series OCLV carbon fiber makes up the frame, producing a very light chassis. Need even wider tires? The Checkpoint SL 6 will take rubber up to 45mm wide, thanks to a roomy fork and a clever "dropped" drive-side chainstay. Got plenty of stuff? Rack mounts, fender mounts and up to 4 bottle mounts let you install all kinds of bags and accessories for multi-day adventures. Are the "roads" barely worthy of the name? The Checkpoint SL 6 has your back with an IsoSpeed decoupler and Ride Tuned seatmast at the top of the seat tube/top tube juncture. This clever technology allows the frame and seatmast to comfortably flex when attacking washboard hardpan, pavement transitions and railway crossings. A stable geometry and a low bottom bracket add confidence on loose surfaces. That comfort doesn't come at the cost of handling and torsional strength, though. A tapered head tube and rock-solid BB90 bottom bracket adds strength for precise handling and flex-free power delivery. An adjustable Strangehold thru-axle rear dropout can adjust the wheelbase by as much as 15mm, offering a longer wheelbase for stability, or a shorter wheelbase for the more classic feel of a road bike. Loose surfaces can mean lots of "roost" from spinning tires, but the Checkpoint SL's Carbon Armor will protect the downtube's bottom from flying stones. Front and rear 12mm thru-axles bring an extra dash of torsional strength for razor-sharp handling.

Shimano’s latest GRX gravel components are a natural choice for the Checkpoint SL 6. The 11-speed “RX800” version of the gravel-specific components provide a durable high-performance drivetrain when heading into parts unknown. Shimano’s 40/31T GRX crankset is paired with an 11-34T Shimano HG-800 cassette, bringing a wide gearing range to every adventure. The Checkpoint's dual-control levers are reshaped for riders spending more time on their hoods, along with a retextured hood surface. Hydraulic disc brakes bring plenty of stopping power and excellent lever feedback to the Checkpoint SL 6.

Bontrager supplies the alloy Paradigm Comp 25 wheels, bringing light weight to the bike with every acceleration. The 25mm interior rim width allows wide tires to spread out for a better footprint, improving grip on loose surfaces. They're tubeless-ready, improving reliability during backcountry riding and racing when set up with sealant. The tires are Bontrager's GR1 Team Issue tires in a 700x40c size; perfect for hardpan, light gravel and rough pavement.

The Checkpoint SL 6's "furniture" starts with a Bontrager Arvada Comp saddle, offering a comfortable perch when traversing technical terrain for many hours -or days- on the road. An alloy Bontrager Elite IsoZone VR-CF handlebar features IsoZone padding in depressions, soaking up fatiguing vibrations. An alloy Bontrager stem has Blendr accessory mounts for lights, a handlebar computer or a GoPro.
