What is different about the frame compared to the previous generation Checkpoint SL?

• New Gravel Endurance geometry is revamped with shorter and higher reach for a more comfortable, accessible and capable all-day ride
• Improved internal downtube storage with more internal volume, a bigger door, and a new BITS bag
• Still maintains the same top tube, frame, downtube, fork, fender, and rear rack mounts of the previous Gen, but now also has mounts for a front rack
• Frame is now better optimized to store bigger volume bottles, even when the new Bontrager Adventure Half Framebag or Adventure Triangle Bag are mounted on the frame
• Bigger tire clearance can now fit up to 50mm gravel tires (as measured)
• Now compatible with 40mm travel suspension fork (all sizes except XS). Assessed compatible models include:
  Rockshox Rudy/Rudy Ultimate, 30mm or 40mm travel
  Fox 32 Taper-Cast, 40mm travel
• Maintains the same IsoSpeed comfort tech as before, but the hardware is now visible
• UDH (Universal Derailleur Hanger)
• RCS Headset System
• More robust chainstay guard

Is the IsoSpeed adjustable?

No

What’s new about the handlebar?

New Checkpoint SL 5 AXS and 6 AXS come with the new GR Elite Handlebar and Checkpoint SL 7 AXS comes with the new GR Pro Handlebar. Both new bars are updated with a more comfortable, ergonomic drop shape. Both bars are now also 6cm wider in the drops than the hoods, have 120mm of drop, and have 15 degrees of flare – all for better control on rough surfaces.

Does it have internal storage?

Yes! And the internal storage area has been improved with more room to store essentials, along with a bigger storage door to get essentials inside the frame.

Is it compatible with a dropper post?

Yes.

Is it compatible with mechanical drivetrains?

Yes.

What’s the RCS Headset System? What stems are compatible with this bike?

The new RCS Headset System simplifies and standardizes the parts needed to cover cockpit setups across models and between platforms:

• RCS Race: For use with the new RSL Aero bar/stem (included with Madone SLR Gen 8 and Checkmate SLR)
• RCS Pro: For use with the current RCS Pro Blendr stem (included with Madone SL Gen 8)
• RCS Universal: For use with traditional round stems

Trek gravel and road frames made for the RCS Headset System will use a consistent headset bearing cover and spacers depending on stem type (outlined above), so you’ll always know exactly what parts are needed to swap cockpits between models/platforms that feature the RCS Headset System. See the service manual for more details and part numbers.

What is UDH (universal derailleur hanger)

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.
