At one point during a stage (can't remember which one), Phil/Paul were commenting on domestiques and how the rules state that riders can only carry 11 bottles, max. I tried this last weekend, here's what I got:
1 bottle in each cage (2)
1 bottle in each jersey pocket (3)
2 bottles down the back of my jersey (2)
1 bottle in my right hand (1)
That's 8 bottles. Where do the other 3 go? Beats me. FWIW, the domestiques they were showing did not have musette bags.
