A 29er will 'roll' beter than a 26, however I'm not convinced that a fat tyre will roll quicker than a thin one in majority of trail conditions.
I had a very long running arguement with a someone a used to work for about this, however if some one can prove this, (technically) I'm happy to change my mind

36er is the way forward

minimising the energy lost to casing deformation,
I take it this is looking at road use. IIRC the data from Schwalbe for off road suggested that it was the ability for wider tyres to deform more, as they could run at lower pressure, that made them faster. The argument being that the increased deformation of the tyre meant the weight of the bike was not being moved upwards as much.
Depends on the trail far more!trail_rat - Member
footflaps - alot of that depends on the rider
TQGraeme - Did the rider in your pic actually make it round the corner? 😕 regardless of wheel size/tyre width that looks to be bloody awful line choice/body position for the particular corner.
and is it necessary to go vegan if i buy a 29er? - cos that's a deal killer right there...
Look at the tyre tracks on the ground.
I'm following pretty much the same line as everyone else.
sort it out your riding and you wouldn't need to look for another tyre/wheel size for an advantage over the rest of the [s]sheep[/s] competitors.
whys that then - last time i looked the trail didnt change when i was following a rider down a bit of trail ....
the only change is bike and rider .....
poor rider on a 29er will be caught by a skilled rider on a 26er - even if it is a 1989 specialized stump jumper ....
Terry, you've completely missed my point.. the riders' skill is irrelevent! as you say, a good rider will fine and a shit rider will still be shit no matter what bike they're on.
unless you only ever ride trails better suited to larger/smaller wheels a 29 will be better in some situations, 26 in others, 20 in others, horses for courses if you like. 😉
With your fitness and the sheer number of events you ride these days I'd imagine you know [u]exactly[/u] which is better for you (as do I) and where.
I realise that the rider has a big effect, but it has happened enough for me to suspect there is a trend there. Not that I have anything against 29ers.

Some of us aren't looking for an "advantage" though.
Just looking to ride bikes that feel right to [b]us[/b] .
There's more to life than being .00005 of a second quicker than the next guy you know. 😉
My 29er has won more races than any of my 26" bikes.
That's simply because the people that beat me when I use my (lighter) 26" bike don't enter the races I use the 29er for (it's my winter race bike).
That said, if I had to have one bike it would probably be my Mamasita 29er - it's great for "just riding". It may even get used at certain Nationals courses this year now I've bought some decent wheels for it.
