the team mechanics seem to prefer the stand that supports the bike from beneath the BB shell
and clamps in place of one of the wheels .

an example like this: http://www.parktool.com/product/supe...e-stand-prs-21

but for situations where its sketchy, LBS has a Park Tool .. that expands like a quill stem, into the seat tube,
to replace the CF seatpost. and then hold that in the stand..

here is the newest version .. http://www.parktool.com/product/inte...be-clamp-isc-4
