But I'm looking at things logically this time. The larger tyre of a 29er gives a larger (longer) contact patch. Combined with say... a 2.4" wide tyre and the end result should be a sand eating machine.
Plus... the SDBC is really a long "fireroad" trail. (with lots of dunes and sand) So "snappy cornering" and the like don't really matter out there.
In fact... I'm thinking that the bigger 29er wheels might be just the thing for the event...
The Salsa Big Mama is up for consideration. 4" (100mm) of travel. Cool colour (though it may just dissapear into the orane/red sands of the desert). Oh and it's made of Scandium.
Still... the Mojo was soooooo nice in 2008...
What to do...??
