As a mostly year-round cycle-commuter, in training:
I have a high end carbon Specialized-S-Works (my
Lamborghini) for nice weather and paved roads
My Cannondale Mountain bike (my
Humvee) for bad weather and icy roads (I don’t do off-road cycling, but I can)
And I’m considering good quality (?aluminum, BMC) for wet roads and rain, from about March through December, and dry winter roads as my (?)
Mustang.
