Trek Checkpoint ALR 5 (2019) review
The Trek Checkpoint ALR 5 (2019) is a high-quality gravel bike. It is designed to offer excellent performance, versatility, and comfort for riders looking to explore a variety of terrains. Here are some key points and thoughts about the Checkpoint ALR 5 (2019):
Design and Build
Frame Material: The Checkpoint ALR 5 features Trek’s Alpha 300 Series Aluminum frame, which provides a strong yet lightweight structure. The frame is designed to be durable and capable of handling rough and varied terrains.
Geometry: The bike’s geometry is optimized for gravel riding, offering stability and comfort. It has a slightly more relaxed geometry compared to a road bike. Thus it helps in reducing fatigue and improving control on long rides over mixed terrain.
Components
Drivetrain: The bike is equipped with a Shimano 105 groupset. It is a step up from the Tiagra groupset found on the ALR 4. Shimano 105 is known for its reliability, precise shifting, and excellent performance, making it suitable for more demanding gravel rides.
Brakes: The Checkpoint ALR 5 features Shimano 105 hydraulic disc brakes. They offer superior stopping power and control in all weather conditions. Hydraulic brakes are known for their better modulation and performance compared to mechanical disc brakes.
Wheels and Tires: It comes with Bontrager Affinity Disc wheels paired with Bontrager GR1 Expert 700x40c tires. These tires provide excellent traction and stability on gravel and rough roads, enhancing the bike’s off-road capability.
Gravel-Specific Features
Mounting Points: The bike includes multiple mounting points for racks, fenders, and bottle cages, making it highly versatile for bikepacking, commuting, and long-distance touring.
Tire Clearance: The frame and fork offer generous tire clearance, allowing for tires up to 45c. This means you can fit wider tires for increased comfort and traction on rough terrain.
Comfort: The bike is designed with a carbon fork. It helps to absorb road vibrations and reduce rider fatigue, enhancing comfort on long rides.
Performance and Ride Quality
Versatility: The Checkpoint ALR 5 is designed to handle a wide range of surfaces, making it a great choice for riders who want to explore different types of terrain. It performs well on both smooth pavement and rugged gravel paths.
Handling: The bike’s geometry and wide tires provide confident handling and stability, even on challenging surfaces. It strikes a good balance between comfort and performance, making it suitable for long rides and varied conditions.
Comfort: With its relaxed geometry and features like the carbon fork, the Checkpoint ALR 5 offers a comfortable ride, suitable for long-distance rides and all-day adventures.
Considerations
Weight: While the aluminum frame is sturdy and relatively lightweight, the bike may be heavier compared to higher-end carbon gravel bikes. However, this is typical for bikes in this price range and does not significantly detract from its performance.
Component Level: The Shimano 105 groupset is a high-quality, mid-tier option that offers excellent performance and durability. While there are higher-end options available, the 105 is well-regarded for its balance of performance and cost.
Overall Impression
The Trek Checkpoint ALR 5 (2019) is a versatile and high-performing gravel bike. It offers a great balance of durability, comfort, and performance. It’s an excellent choice for riders looking to explore a variety of terrains and who want a reliable bike for bikepacking, commuting, and long-distance touring. The Shimano 105 groupset and hydraulic disc brakes provide excellent performance, making the ALR 5 a solid upgrade from lower-tier models. If you seek a capable and adaptable bike that can handle diverse riding conditions, the Checkpoint ALR 5 is a top choice.
