See that below? That is a number pin. That is what pins do. We'd all be better without them. Good example. Murrietta 2014. Daniel was the Cat 3 Omnium leader at this point. SRAM was neutral support and would not take other wheels (actually they did after some begging seeing they did not have a 14T 11speed). If this had been a rear flat (it was a front) would he have been cheating if they gave him an illegal rear and he maintained his lead? My answer - same as before - its up to the referee.
