Most memorable that I saw myself o tv, hmm:
1) Cav vs Hushovd in the TDF green, culminating in THAT break by thor, and then renshaw/cav on the champs elysee
2) Contador winning the TDF by a mile, inc some of the best climbing displays ever, esp all the ones where he dropped LA
3) Cav vs Haussler at MSR
4) Shouting at my telly when the slug (Vino) went off the front of the WC peloton, only for crazy Johnny to pull him back in, and drop him. Crazy Johnny became a hero that day for shoving it to one of the most despised cyclists
5) Fabfab, just everytime, especially the Worlds TT, and then the display of power in the RR, which, if the restof the mini break had been prepared to put in any work, could have lead to a Worlds double.
and a bonus one as i couldn't not mention it
6) Feilleu the younger winning that stage in the TDF, one of the best i have seen, and good to see la belle France having a rider finally to cheer o who could win things, rather than just go on doomed breakaways (yes, slyvain and tommy v, i am looking at you!)
