I am getting a new frame to fit me better.  I bought the 17" bike without ever trying it off eBay 2 years ago.  My 1998 Stumpjumper was a 17, so I bought a 17, not accounting for the extra travel on the suspension and the higher overall height due to the 29" wheels.  Went from 1.5-2" of clearance to no clearance. I rode this bike for 2 seasons, then bought my son a 13" Motobecane 29er - Fantom 29er Pro - one level down from the link posted.  I also like Shimano a lot more than SRAM.  His XT group just feels better than my XO/X9 group does to me. 

That thing fit so much better, but a bit small - hence the 15".

I think I am going to just sell the Stumpy and go custom build.  I have a Motobecane fat bike and my old 26 Stumpy (and a DJ bike), so I can take my time and hunt for deals.

I am looking at replacing the 17" frame on my 2010 Stumpjumper Carbon Expert 29er with a 15" frame.

Does anyone know of a web site or other article that gives an overview on frame selection and what I need to "match" to make sure my components transfer over (bottom bracket style, rear width, headset, etc?).  I would like to simply swap items and not have to buy too much in addition to the frame to make this happen.

Thanks!
