If you haven't already, the Tim Bird ride report, "Boggle Hole and Back," Spring 2013 Bicycle Quarterly 47-60, is a real treat. That's a ride report by a guy who knows how to report.
Whenever I read that sort of report I find myself surfing the web looking at the rando-specific rigs like those custom-built at Boulder Bicycles and Firefly, this cool new titanium maker to which D__ alerted me. You know the type -- tires fatter than the tubing, bars level with the saddle, full integrated fenders, maybe even friction shifting on the down-tube, bar-ends or grips, and generator hubs.
Time for the views of the commentariat: let us look for justifications! I (we all, let's admit it) have different bikes for several purposes, up to and including "in case Sam comes to visit." (This despite the reality that my best performances in biking and triathlon all have occurred on the Gunnar -- perhaps the least likely rig in my stable, per modern marketing literature.) Does a world exist in which it makes sense to purchase, to build, or some combination thereof, a _pure_ rando rig? If so, what does one need and what can one leave off?
