I know it's been covered before, but today's stage 5 winner, Mark Cavendish, tucks it in. Makes it hard to wear bibs (favorite of all of my cycling apparel). Perhaps weight weenie? You would think, but not with those Pcad-esque socks. Not as baggy, but certainly as tall as Michael Cooper's socks when he played for the 80's Lakers.
Posted here because, although it is a TDF image, tucking in your jersey has been covered in this forum. Ok for racers, but not for the everyman?
