my current stable consists of 3 bikes and i regularly commute with each of them:
- road bike - fair weather commuter
- IGH/disc brake hybrid - foul weather/winter commuter
- folding bike - when i have plans after work so i don't have to street lock one of my other bikes
My ideal stable would have a couple additional bikes:
- CX bike with disc brakes - i'd slap some fenders on it and make it a dedicated rain bike, then i could just leave the studded tires on my hybrid and it would become a dedicated winter bike.
- Surly Moonlander - a dedicated heavy snow bike. this would be more novelty than anything as it doesn't snow a whole hell of a lot in chicago , but i rode one at a bike show last spring and i want one!
