I have a 2004 VooDoo Wanga with a Surly rigid fork on my hands that is my current project. Its going to be my commute bike with slick road tires, disc brakes and internally geared hub.
I have a 26" wheelset on it right now with 1.2" wide tires and it just plain looks goofy. Tires look tiny because theres so much clearance on the frame. The frame was built with super wide knobby mountain bike tires in mind so this makes sense.
So it would make sense to me to then switch to 700C wheels with narrow tires and that would bring me back close to spec for frame clearance and geometry. Since I'm using disc brakes, no worries about brake reach.
Is this sound thinking? Any holes in the plan?
