>>1790178>- stitch the laminar flow back together behind the trailing edge (seat bags/fairings, rear disc wheels)There is no laminar flow on an upright bicycle. Also, you cannot "stitch laminar flow" back together, unless you use some kind of active boundary control like hundreds of tiny holes or generate a vacuum using a fan. That would only work on a velomobile.
Even airplane wings are only laminar flow for the first 10-30% of the wing. Once the wing slopes back down, the flow becomes turbulent. High-performance wings are designed to recapture the turbulent flow and limit the amount of time the airflow is in transition. They don't use active boundary layer control because it's complicated and doesn't improve performance.
You want to minimize the height of the boundary layer to reduce drag. Not the same thing as laminar flow. Also, if you're riding on a concrete road or within 100ft of another rider, the air is probably not even laminar to start with, anyway.
