where you actually meet WCD
WCD is the drivetrain you can fix in the pit with a wrench. Cantilevered wheels mean you can swap one without dismantling the frame, the chain runs protected inside the rail, and there is nothing to re-zero before a match. Teams still choose it deliberately when reliability and a short build timeline matter more than the ability to strafe.
Free and structured, and none of them need an account to read.
