I have three different bikes and out of those three my Surly 1x1 frame is what I can call a 'do it all frame'.This frame has lot's of clearence, 26" wheels, 650B wheels, or narrow 29'er wheels all fit with ton's of clearence for full fenders. A choice of disk brakes or cantis. I can set it up as a singlespeed, fixed gear, IGH hub or with special adapter even a deraileur will work. Very easy to mount racks and fenders. This frame can be customized to do just about anything: commuting, singletrack, long distance rides, touring. Yes there will always be some little compromises but to me it's the most versatile frame I've ever had.
