Hi Guys: Just took delivery on the above and they look aggressive enough for light dirt and gravel in addition to the mucho paved I ride. Saw an "old mad max" 10-30-13 posting. At least at that time he seemed happy with them. Would be interested in other observations as we have recently been dealing with the more decidedly off road versions for the bike. Will be waiting for spring probably to change out, but who knows? What about a bit of discussion of these alternatives. And, as an aside, I really liked Werloc's statement recently that we sometimes do truly "over think" issues with this bike. But what the F..., it's an addiction. Also we can't over think other bikes as they have already done it for us. The TW is the workingman's 1950/60 car equivalent. It needs to be modified, and can because it's not totally the end product. That's the beauty in my mind.
