It's true that we here at C.A.N.R.S. have been slightly critical of the UCI's sticker approval program in the past. So it's not surprising then that a bike gets used in one of the biggest races of the year without apparent approval...
|Here is Antonio Piedra's "ViVelo".
He rides for Caja Rural and just won a stage of the Vuelta.
There are no photos on the ViVelo site that show a sticker and
more importantly, the frame is not listed on the UCI
"approved frames" list.
