The Trek Checkpoint is the only bike you need to take you on every adventure
SRAM Rival AXS is the perfect groupset for an all-arounder
Mud-guard mounts
Mounting points for every bag you can think of
Non-proprietary seat-post provides options
Internal storage is convenient
Downtube protection eases worry
Threaded bottom bracket
Ideal all-around gearing
Short stem for added stability means handlebar/knee interference
Lacks included protection for the chain stay
Detail behind the fork steerer collects water and is difficult to clean

Trek's updated aluminum Checkpoint is a surefooted, confidence-inspiring ride that's perfect for ruined back lanes, byways and well-laden travels
Stable and predictable
Comfortable
Great shifting and brakes
Gearing a bit tall for the weight
Could use a dropper post

Effective geometry
Sensible spec
Neat extra frame features
Comfortable
Heavy
Non-removable front derailleur mount
Headset cable integration design isn’t watertight
