I also don't subscribe to the 'winter' bike nonsense
is it REALLY such an imaginative leap? The drivetrain on my "summer" bike is worth more than my entire "winter" bike, so it is cost effective to ride a second bike in lousy conditions, and saves faff time unless you intend to leave heavy mudguards on your lightweight bike 12 months of the year. As ahwiles says, one dirty/damp winter road ride and everything that can corrode will. My "summer" bike does get used on nice dry winter days, but my winter/commuter ploughs on with a regular blast of GT85 and not much else, when stuff wears out its cheap to replace.
Deadkenny, poor trolling, there are ~2.3 million threads in the STW Bike forum alone and yet you post in a thread of no interest to you, have you really exhausted every mountain bike specific thread? Give it 5 minutes there'll be another "what tyre" or "which flat pedal shoe" thread along for you to get a fizzy feeling over.
