The only way I can describe it is "wheel flop". I recently converted a 26 in. mtb into a 29 in. front, 26 in. rear 96er (or 69er, which ever way you want to look at it) and noticed that in slow turning the front wheel seems to want to pull down more into the turn, whichever way you are turning. Now is this due to the different diameter wheels or the fact that the front end is now higher (more relaxed head tube angle), and just needs to be used with a shorter crown to axle fork length to eliminate this wheel flop feel? Thanks.
