Trek Checkpoint SL 6 AXS review – all-round gravel machine

Oct 2023 · Guy Kesteven

Trek’s Checkpoint has unique progressive geometry and scissor frame features and all the mount points you could want. But is it a multi-surface, multi-mission master or a complicated compromise?

Highs
  • IsoPulse Decoupler is a significant ride smoother

  • Well balanced road or rough handling

  • Efficient speed on all surfaces

  • SL 6 model is a real performance for price sweet spot

Lows
  • Saddle is a bit squishy on longer rides

  • Many mounts mean slightly more mass

  • Controls go through the headset

  • Non removable front mech tab

  • Rough rear hub
