15.5" huh? - I wonder what the one I tried out was. Musta' been bigger than 16". Purple marlin, huh?...must be a closet ECU fan. I was out at the Bicycle Post trails here in town today - first time out on the trails in a while. I haven't made it out to the triangle to try any trails out there. Heard there's some good ones out that way. The Post trail is pretty decent - they've got it up to about 10 miles now or so. It sure worked me pretty good today.
