Naw, MTB frame with a suspension fork, but mostly slick tires (1.5 in back, 1.75 in front)
I worked out the gain ratio between my ride and a randomly selected specification for a roadie with a tripple and discovered that I spent the whole climb in gears that are too granny for a road bike. So I'm not totally sure if a roadie would have made it any easier. Any weight loss moving to a roadie would be offset by the fat that I have yet to get rid of in my beer gut.
On the other hand, the Wirehead of 2 years ago would have bailed after a few hundred feet, even with a granny gear. I have come a long way.
