Anyone have any experience using TBT with HED or FLO type wheels? Do they hang the bike off the wheel. Which I never do with the HED's.

Also regarding having a disc wheel on during transport, I am little confused, they state "We DO NOT allow full carbon disc wheels to be transported on bikes. You may transport your full disc wheel in a wheel bag. Please place another wheel on your bike for transport. All other race wheels (e.g. 404s, 808s, 1080s) and race wheel covers are safe to leave on your bike."
So disc covers and non structural discs like HED are fine? That seems odd to me. Any reasoning?
