I noticed the Astana team have been riding in jerseys devoid of sponsors' logos, apart from a tiny "Trek" on the shoulder. Now I know Astana have had their troubles, so it doesn't surprise me. I assumed they'd had a job lot of jerseys made up in team colours minus logos. Until David Harmon pointed out they were "faded out", and by jove, I did see a faint "Astana" where you'd expect it to be.
What did they do - bleach them out specifically? Paint over them? Weird.
