I checked out an 18" Reign 3 at the LBS yesterday- nice bike. I measured the top tube though, out of curiosity, and it came out to approx. 22.7"- virtual top tube (on the horizontal, center-to-center of head tube/ seat post, the same way Giant supposedly measures it). Kinda short for an 18", sadly. Anyone else measure an 18" or other size and find some discrepancies? I remember reading JM. finding the chainstays and wheelbase to be off from published specs as well...
