I commute near-daily, 11 mi round trip. I haul the bike in to work on Monday and leave the truck overnight as often as I can, giving me use of the truck during the day. I'm on a 2002 Specialized Hardrock which I bought new, now kitted out with a big Electra ding-dong bell, slick tires and a large tail bag. I find it a bit leaned over and small wheel and might replace it sooner or later with something like an FX.
But more importantly I'm putting my Dad's 1976 Schwinn Paramount P10-9 back together. Although some marketing said 1-1/4 tires, I found that Panaracer Pasela 630-32 tires very nearly don't fit. But supposedly there were optional fenders. Go figure.
At one point I had a slick little Cannondale CAAD-something Saeco team replica bike. Bought used, sold for profit. Never learned much about it but liked the speed. Sold when I had some health problems that prevent me from really pushing my limits.
