Frank Schleck has had a positive test result for the diuretic Xipamide at the Tour de France. To date, there is no explanation by Schleck. The recent CAS decision (attached) relating to Alex Kolobnev, who tested positive for a banned diuretic at last year’s Tour, and was later cleared by CAS on the basis of “no significant fault” may prove to be a guide for the outcome in this case.
