I am waiting on a 2006 Specialized FSR Stumpjumper Pro thats on order and this because after months of trying to buy a 2005 FSR S Works I wasn't having much sucess this lead to some research on the elusive M 5 Tubing that is the main selling point of the S Works frame ang found out that the catalog and web pages very carfully choose there words " M5 manipulated alloy DT with Transform monocoque TT" The Down Tube is the only tube on the entire bike that is M5 tubing the rest of the bike is the EXACT same tube set as the Pro !! one tube for $1000 thats great marketing hype ! At least after 45 minutes on the phone they ( Specialized tech support) did admitt this to be true ! And after another disapointing year of sales of the Epic, it entire line( even the base rim model) gets quote " M5 alloy fully manipulated frame" however that since they sell out of the FSR stumpy every year we only get one tube on no less than the S WORKS !! Must be some goooddd stuff that M5 tubing !
