Why would anyone want to run tires that hard? Do people have an aversion to traction or something?

That Vicious is nothing like what I imagine as a urban speedster. It looks to me like a yuppie bike for executives who want to ride around the lake with their kids on the weekend. Not bad paintjob though. Down tube panel is too close to the head tube, but I guess I'm being pedantic.

Now that I think about it, Discs might be overkill, but the attraction of never having your rims wear out has got to be attractive for those that do the big commutes. Hrmm.

Okay. 700c. Titanium frame, mtb style singlespeed. Room for 35c with fenders, rack mounts. Cable discs. 135mm rear spacing. Weird bars. Rigid? probably. Hrmm....Maybe V-brake rear with the Paragon horizontal dropouts with derailleur hanger? So you can at least run gears at the back if you must?
