its a conversation off of a question sent in by others . most of that is not fake. there were points where they actually talked.

Made a couple good points and cleared things up for ill informed people.
Despite what everyone says or does, it all comes down to personal preferance.
(cuz I run a very short rear end and my manuals are dialed)

So, i guess frames are like brains, it really doesn't matter how big, but how you use them...

well if you are like 6.5 feet you wont fit in a 20 tt, but i think that the geometry doesnt really matter, its is just to get use to the bike
