This super cool mullet Sram gravel build is a 1 of a kind rig. We did the hard work of converting the Sram Force 1x11 shifter to make it work with a wide range Eagle rear derailleur. Drop bar Eagle mechanical is classic shifting with a modern twist.
The tech you get A 700 Series OCLV Carbon frame with IsoSpeed and carbon armor, a progressive geometry that's stable at speed and efficient when you're grinding up a climb, internal storage, hidden cables that won't interfere with bags, and integrated frame bag and fender mounts. Plus, a carbon fork, 1x12 Sram Mechanical Mullet drivetrain with a wide-range cassette, and Bontrager Aeolus 37V carbon wheels with wide gravel tires that provide extra traction and stability. Fits up to 45c tires.
The final word Our best Checkpoint frame is designed and built for performance and comfort during grueling gravel races. It's ultra light, fast, and comes with premium parts from Sram and Bontrager carbon wheels.
