No it doesn't... But i only have size 10's so if you have 13's or something then... Your still probably be good!

Yeah, it's lush to ride... Super easy to manual, only having 390mm chainstays (not the shortest, but still shorter than most)... If by 'fat boy' you mean the tubes are over sized, then yes, but heavy, no... Mine weighs 2170g (4.8ish pounds) for the frame only, so no i wouldn't class it as heavy! Head angle is fairly neutral at 69 degrees, but it's a good angle for me =)... I have even used it for downhill (over-taking some full-sus guys on the way down! =P) However it is a stiff mo-fo so be-aware... Also when the wheel is slammed in the chainstays, the biggest tyre i could get in height-wise was a twin rail (26"), otherwise it touches at the seatstay brace (which looks beast!) Hope this helps...

Got 22-10 now (Ha!) =)
