I recently purchased a mountain bike for touring conversion.
It was pointed out to me recently that this bike did not have a double butted (or even a butted) frame. I am a larger guy and weigh around 250lb. (think former college lineman here). My question is this: Is the lack of double butting on this frame going to be a serious drawback to mostly on road touring for a guy of my size? I suppose I could swap the frame out for a Surly LHT in a pinch without too much trouble.
The bike is a Giant Iguana 640 which was a cheaper knockoff of the Iguana. It has a 4130 chromoly steel frame/hi-tensile steel rear stays. I know not all Yukons are double butted and these seem to do OK for tourer conversions. It is a mountain bike after all, and I suppose I can count on some structural integrity due to the off road intention its designers had for it.
So whaddya think? Is double butting essential for a touring frame? I want to be reasonably sure I can use this bike before I put any more money into it.
Any info is appreciated as always.
