I have been doing research on this 29er thing. Test rode a full sus 29er, and the rolling was great. Has me wanting to build up a SS29er. Well anyways, I noticed that some refer to them as 28 inch tires, like the Fat Alberts by Schwalbe. Funny on mtbr's 29er forum, some hate hearing the 28 size reference. It wouldn't get the same backlash as posting in here that you just got the sweetest track frame ever, and added a back brake mount, back brake, and a freewheel.
