Just maybe the most comfortable balloon-tire "road bike" around? A monster crosser? A road bike for really bad roads? Who knows? Anyway, some build notes: the 29er frame (from performance bike) cost less than $90. The 80mm travel manitou fork was a closeout and also pretty cheap (but it cost more than the frame). The wheels, based on shimano XT disc hubs, were hand built. Most everything else came from ebay. The drivetrain is basically a shimano 105 road triple group that I set up to work with a compact double crankset (but using a triple octalink BB). Via a custom modification (the addition of a small alloy arm fabricated from thick hardware store sheet aluminum), the road front derailleur now works as if it was designed as a top pull instead of a bottom pull.
