have there been any doping cases in MTB? missed tests, TUEs, othet mishaps?
I was following the downhill worlds here in Italy and I was wondering if MTB has/had doping issues
Yes (of course

). One that springs to mind is quite recently a famous South African mtber caught for epo. Evans.
Was discussed in the S.A. racing scene thread.
I think there is also a mtb doping thread where you'll find more cases.
I'm not sure but I think Ryder hesjedal has also admitted to doping during his mtb career.
