Design and Build
Frame Material: The Checkpoint SL 5 features Trek’s 500 Series OCLV Carbon frame, which strikes a balance between lightweight construction and durability. Carbon fiber provides excellent vibration damping and responsiveness, enhancing comfort and control on rough terrain.
Geometry: The bike’s geometry is optimized for gravel riding, offering stability and comfort over long distances. It typically features a slightly longer wheelbase and more relaxed angles compared to road bikes. That is why it provides a stable and confidence-inspiring ride.
Components
Drivetrain: The bike is equipped with a Shimano 105 11-speed groupset, offering precise and reliable shifting performance. The 105 groupset is known for its durability and smooth operation, making it well-suited for gravel riding and long-distance touring.
Brakes: It features Shimano 105 hydraulic disc brakes, providing powerful and consistent braking performance in all weather conditions. Hydraulic disc brakes offer excellent modulation and control, enhancing safety and confidence on descents and technical terrain.
Wheels and Tires: The Checkpoint SL 5 comes with Bontrager Tubeless Ready wheels paired with wide Bontrager R1 Hard-Case Lite 700x32c tires. These tires strike a balance between rolling efficiency on pavement and traction on gravel, making them suitable for a wide range of surfaces.
Gravel-Specific Features
Mounting Points: The bike includes multiple mounting points for racks, fenders, and bottle cages, allowing for customization and versatility for bikepacking, commuting, and touring.
Tire Clearance: The frame and fork offer generous tire clearance, allowing for tires up to 45c. This provides the flexibility to use wider tires for increased comfort and traction on rough terrain.
Comfort: The carbon frame and fork help to absorb road vibrations, reducing fatigue and enhancing comfort on long rides.
Performance and Ride Quality
Versatility: The Checkpoint SL 5 is designed to handle a wide range of surfaces, from smooth pavement to rough gravel paths. It excels at gravel riding, offering a smooth and stable ride even on challenging terrain.
Handling: The bike’s geometry and wide tires provide confident handling and stability, allowing riders to tackle technical sections and descents with ease.
Comfort: With its carbon frame and features like the IsoSpeed decoupler, the Checkpoint SL 5 offers a comfortable ride, minimizing fatigue on long-distance rides and rough terrain.
Considerations
Cost: The Checkpoint SL 5 is a high-end gravel bike with a premium price tag. While it offers excellent performance and versatility, it may not be suitable for all budgets.
Weight: Carbon frames are generally lighter than aluminum frames. Still Trek Checkpoint SL 5 may be heavier than higher-end carbon gravel bikes. However, its performance and ride quality justify the weight.
Overall Impression
The Trek Checkpoint SL 5 (2019) is a top-tier gravel bike that offers exceptional performance, versatility, and comfort. Its carbon frame, Shimano 105 groupset, hydraulic disc brakes, and gravel-specific features make it an excellent choice for riders who demand the best in terms of performance and ride quality.
