I'm glad to hear you enjoyed your first Audax, Dave.
It is addictive, you have been warned.
Any advice on good responses to the opening gambit 'no proper audaxer needs a 53t front chainring' will be much appreciated...
Ah, you see there is always some well meaning soul who is keen to offer you a well placed, unsolicited word of discouragement. "Proper Audaxer", what complete and utter cock dandruff.
My suggestion is that your response could be to just stare at the 'proper Audaxer', move up to him, take a big sniff and say "I don't know how to break this to you but you really do smell of BO and yes, *sniff again* stale wee. Do you mind starting a bit early? It's just that when it starts to warm up I expect you'll really start to stink like a dead Badger."
Never fails and with a bit of luck he'll leave his Brevet card behind as he storms out muttering on about the good old days etc...
Hope this helps.
