Propulsion is possible: the 840 650c Tubular Track disc wheel by Zipp
Zipp is in the business of helping people win races, and some people use smaller wheels. So they've scaled down the classic 900 to accommodate 650c riders who are just as worthy of a disc that's wickedly fast, freakishly light and offers an incredibly smooth ride. Now that you're on an even aero-playing field, the competition better look out.

Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of Zipp's carbon rims. ABLC smooths airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four times more dimples than before.
Carbon Bridge uses a Kevlar® thread in a co-axial helix stitch to bind sheets of carbon to each other in Zipp tubular rims. Because Kevlar is 350% more impact resistant than carbon, it can disperse shock more evenly throughout the carbon laminate, making for a rim that is practically bulletproof. In particular, Carbon Bridge reduces the vulnerability of the rim's tire bed, the area most susceptible to damage from impact.
