Trek Checkpoint SL7 gravel bike - first ride review

Jun 2020 · Laura Weislo

On early impressions, Trek's flagship gravel bike, the Checkpoint SL7, looks perfect for seekers of versatility and adventure

Highs
  • Lightweight, agile and responsive ride

  • IsoSpeed shock adds comfort

  • Underbody protection for the eye-popping paint job

Lows
  • 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

2019 TREK Checkpoint SL6 Review

Mar 2020 · Dale Tiessen

Out of the saddle putting down maximum power into the Checkpoint, it feels like a nice carbon road bike.

May 2019 · Robin Wilmott

Although not the most rugged explorer, the Checkpoint SL6 will go almost anywhere, quickly and in comfort

Highs
  • Fully-featured, practical frameset, IsoSpeed, carbon wheelset

Lows
  • I’d prefer to have 40mm tyres supplied

Trek Checkpoint Review (SL6): Dirt Road Rocketry

Nov 2018 · Joe Cruz

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

Highs
  • 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

Lows
  • 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

Sadly disappointing gravel bike debut from Trek, though fine if you want a fat-tyred road bike
