FAQs

Is this Checkmate SLR gravel bike different from the Checkpoint gravel bike?
Yes, Checkmate is a dedicated gravel race bike, while Checkpoint is best suited for gravel riding and adventures. Both bikes are fully capable on gravel surfaces but do have different features and intended use cases.

What’s different about the Checkmate SLR frame compared to the Checkpoint SLR frame?

  • Checkmate SLR has a Gravel Race Geo that puts riders in a more aggressive riding position for fast racing vs Checkpoint SLR has a Progressive Off-Road Geo which is longer and more upright for stability
  • Checkmate SLR does not have internal frame storage
  • Checkmate SLR has fast and light Full System Foil aero shapes
  • Checkmate SLR uses 800 Series OCLV Carbon vs Checkpoint SLR uses 700 Series OCLV Carbon
  • Checkmate SLR does not have internal downtube storage to save weight vs Checkpoint SLR does have downtube storage
  • Checkmate SLR is overall lighter and faster than Checkpoint SLR
  • Checkmate SLR comes with a one-piece aero and ergonomic bar/stem vs Checkpoint SLR comes with a two-piece cockpit system
  • Checkmate SLR uses UDH and RCS Headset System for compatibility
Does this bike have aerodynamic tube shapes?
Yes, Checkmate shares Trek’s latest and greatest Full System Foil aero tube shapes that were rolled out on the Madone Gen 8 to help make it Trek's fastest gravel bike ever.

Is this bike compatible with the RSL Aero Water Bottles and Cages?
Yes, it is compatible with the new aero bottles and cages, and they are available for purchase; however, the bike does not come with them.

What bar/stem does it come with and what are the features?
Sharing race DNA with Madone, Checkmate comes with the same aerodynamic, lightweight and ergonomic RSL Aero Bar/stem as Madone Gen 8. However, Checkmate does come with a wider bar/stem size for each bike size than Madone to allow for better control on gravel surfaces, while keeping the rider tucked in an aero position.

Does it have downtube storage?
To save weight, it does not include downtube storage. However, it does include mounts for the Adventure Top Tube Bag and Adventure Triangle Bag so riders can easily carry and access all the nutrition and gear needed for one-day gravel races.

What mounts does this bike have?
It includes mounts for: mudguards, 2 frame water bottles, 1 bottle on the underside of the downtube, Adventure Top Tube Bag and the Adventure Triangle Bag.

Does it use UDH, and what does UDH (universal derailleur hanger) mean?
Yes, it does use UDH. The Universal Derailleur Hanger consolidates thousands of hanger options across the industry. It protects your derailleur against chain jams by pivoting back and out of the way and slips slightly when encountering impacts. It improves shifting performance, guarantees better alignment and works with all drivetrains. Plus, if you ever need a replacement, it will be available everywhere.

Is it compatible with mechanical drivetrains?
Checkmate SLR is only compatible with electronic drivetrains.
