I've thinking about replacing my current ride with something with the following requirements:
1) Steel frame and fork
2) Disc brakes (on the chainstay in the rear would be nice but not required)
3) Room for at least 38mm tires with fenders
What I have found through my own research are the following options:
Gunnar Fast Lane (nice but WAY expensive)
If I drop the requirement for disc brakes, I can obviously add a bunch of others including Surly LHT and CrossCheck, Rivendell AHH and Sam Hillborne (again nice but WAY expensive) among others.
I won't be doing much touring with this. Mostly a commuter. I prefer steel to aluminum, and I'd really like disc brakes as I ride rain (and snow) or shine.
