What he said, if you’re happy why do other peoples choices upset you?
I’ve got a tourer/commuter with 32c tyres and propper guards. The best the racer can manage is 25c and guards held on by zip ties.
Wet boots, knee warmers and grit get ground into the stays and top tube and generaly ruin the finish. Crashes are far more likely. Potholes grow in size, number and get hidden under big puddles making them harder to avoid. Drivechains take a pasteing.
And even the frame material, it’s not (just) carbon that suffers in winter, if anything i’d rather my winter bike was carbon as my cannondale is showing signs of the paint bubbling off where salt’s attacked the aluminium in previous years, and steel rusts.
Basicly if you’ve got a nice bike that you like, winter hates it.
Some people solve it by buying a cheeper raceing bike (maybe you race a supersix evo dripping in bing, and have a CAAD10 with crud guards or raceblades). Others go the whole hog and get a lightweight tourer (I’m thinking guard and rack mounts and clearences for 32c tyres, but keeping more nimble geometry).
