Seeing as you have the facts at hand would you mind me asking what we won last time that we didn't win this time? I hope it isn't womens team pursuit.
I think Wiggo in the time trial
EDIT: it's more complex than that. Changes as follows:
In 2012, Wiggo won the time trial, Froome got bronze, in 2016 we just got bronze (Froome)
Men's RR - no change, no medals
Women's RR - Armitstead got silver in 2012, nothing this time around
Women's TT - no change, no medals
Men's team sprint, men's individual sprint, women's team pursuit, men's team pursuit - gold in both years
Women's keirin - Pendleton won, Becky James came second
Women's individual sprint - Pendleton got silver, let's see what Becky James and Katy Marchant do
Men's keirin - Hoy got gold, Kenny let's see
Women's team sprint, no medals in either year
Men's omnium - Cav's silver was an upgrade on Ed Clancy's bronze
Women's omnium - Laura Trott should retain her title
No medals in 2012 in mountain biking or BMX, but we have chances in the BMX
