Enjoy him/her/it
Me and my XTC got one pretty quick even though he's a size too big.
Shimano components really are bomb proof, so are Thorn frames.
The only thing you get in bad weather is:
More chaincleaning (esp. salt)
More frame care (Vaseline is a very good cheap way to protect your frame)
More touch up (Bah, stone chips!)
More leather care (Hmmm leather grease)
Re tires: Panaracer Pasela tourguard tyres are very good, but became harder to get now as Panaracer renamed their tires. Schwalbe Marathon are very heavy but absolutely bomb proof. PP are a good compromise. I will be going for Conti City Contact to try.
