I've just found this part of the forum and I'm surprised I wasn't cross-posted here. 6 ft, 250 lbs. Usually uncomfortable on road bikes, looking for something for rough urban riding, odd trail possible, tempted by Surly (cross-check?) and ss/fixie. Speed and agility would be great, desperately need something where the wheels won't pop. Only just come across the Clyde world and feel like I've come home...everyone I see riding on the levee is so bloody skinny.
