When I wrote that, I was tossing about both effective top tube length and frame reach in my head. Reach just simply came out the winner at that moment. <grin>

And some don't give the effective top tube length. Which is not the same as top tube length, though many label top tube length when they are actually giving effective top tube length.... so see, top tube is confusing to those that don't know, and frame reach has always been frame reach.

As long as the bikes being compared are all the same basic type, road bike to another road bike, TT bike to another TT bike or cruiser bike to a cruiser bike, then the comparison will be close enough. However to simply rely on reach and stack or effective TTL and stack, will still lead one to picking the wrong bike if they have finicky preferences. Some people seem to have troubles with things that don't feel initially like what they are use to.
