Summary
The Trek Checkpoint is a versatile gravel bike praised for its speed and comfort, featuring IsoSpeed technology that smooths out rough terrain. It offers agile handling and stability, making it capable on both tarmac and gravel. However, some reviews note issues with cable routing and gearing that may limit off-road performance.
IsoSpeed decoupler provides excellent comfort on rough surfaces
Versatile with multiple mounting points for accessories
Agile handling and stable geometry for confident riding
Fast and efficient performance on varied terrain
Cable routing can cause contact with knees or frame rub
Gearing may be too tall for steep off-road climbs
Tire choice is often conservative, limiting off-road capability
Front end can feel harsh compared to the rear IsoSpeed comfort
IsoSpeed undoubtedly works. The back end of the Checkpoint was as comfortable as any that I’ve experienced on a performance oriented bike.BIKEPACKING.com
Call me converted as I can confidently call the Checkpoint WSD Queen of the Quiver.
Whatever road or trail you choose, this Trek is all about speed.
The Checkpoint is the cream of the gravel bike crop and a beautiful, lovingly crafted piece of art designed for riders who demand nothing but the best.
Sadly disappointing gravel bike debut from Trek, though fine if you want a fat-tyred road bike

Gravel bikes abound, but this one checks all the boxes, and at a great price.

Jun 2020 · Laura Weislo
On early impressions, Trek's flagship gravel bike, the Checkpoint SL7, looks perfect for seekers of versatility and adventure
Lightweight, agile and responsive ride
IsoSpeed shock adds comfort
Underbody protection for the eye-popping paint job
SRAM Force eTap AXS 1X drive not suited to mixed road/gravel
Top tube is too wide near the seat tube
Toe overlap in the smallest size

Late last year my beloved yet ageing gravel bike, an Orro Terra, became the apple of someone else’s eye. While I had my nose in the computer (probably editing a video) at the library, someone swiped it. Some savvy scumbag broke the lock and rode away. I’ll also add that said scumbag must be a […]

Full disclosure, this is my first gravel bike. When gravel bikes entered the scene a few years, I initially remarked to myself this was another bike industry push to create something new and drive sales.

Although not the most rugged explorer, the Checkpoint SL6 will go almost anywhere, quickly and in comfort
Fully-featured, practical frameset, IsoSpeed, carbon wheelset
I’d prefer to have 40mm tyres supplied

Joe tested the Trek Checkpoint SL6 on weekly fast roadie coffee shop rides, a 10-hr dirt randonee, and VT gravel/singletrack explorations. Here's the review
Feels like a road race bike
IsoSpeed coupler absolutely smooths out jolts
Thoughtful design touches, including a variety of bosses for cages, armor under the downtube, bosses for a gas tank bag
Very capable on tarmac alongside its gravel prowess
Feels like a road race bike
650b conversion not recommended
Unusual routing can cause cable contact with knees depending on out of the saddle pedaling style; might also interfere with feed bags
Long inseam riders may reach the end of the saddle height adjustment
Purpose built for speed rather than maximal bikepacking versatility

The new Trek Checkpoint gravel bike covers all the bases off road and on, making it a versatile, adjustable option that could replace several of your bikes.
