Bike porn

120 was hyperbole on my part; my point was that people I know are thinking about going rigid if they add a niner to the fleet, so any travel allowance is too much.

Read this on bikemagic. Its regarding full sus 29ers, but it makes a good point.

We remain a little unconvinced by 29in "sturdy" suspension bikes, on the whole. 29in wheels undoubtedly have benefits, but those benefits are most keenly felt on hardtails and short-travel bikes. The more travel you add, the more the "29eriness" gets diluted. Much as 26in bikes will always be lighter than 29ers, so you'll always be able to package a bit more travel into a bike with smaller wheels. If your riding tends to use up suspension, 26in is probably the way to go.

I've read about the massive offset you need to get alot of travel out an 29er fork too, without using mad headtube angles. Not sure I like the sound of that.

The fork has the monster offset that forms the key part of Fisher's G2 geometry, which sorts out the steering of 29ers without resorting to crazy-steep head angles. We've found other G2 bikes to be amazingly handy tools, but you have to get used to the disconcerting lack of steering feedback - initially it feels like the bars aren't actually connected to anything.

I suppose the 'if your really tall' argument may still stand up. But being really tall is'nt something I know much about :)

For me 29ers suit being fully rigid.
I've a particular 26" full sus on my wishlist.
