Abarth, the fact that every other Shogun of that year and model that I've seen has different seatstays and more (any) water bottle braze-ons, has me convinced that you are correct.
Shrinkboy, you obviously have normal legs. What's your inseam on pants? 35 or 36 when you buy your Levis, huh? The BF kept telling me that he had extremely short legs, but he's very big-boned and powerfully built and I just didn't see it. Until we measured. When he stands over the Shogun, he's got an inch of clearance. Now that may not be perfect. Might even be a bit small (he could certainly ride a 54cm bike, or even a bit bigger), but for someone who is casually riding on occassion, I think it will work just fine.
