Of course Viggen is using a fs 26 for all mountain riding…what else would you use? there is like one company that makes a true “all mountain” 29er (niner) and it is sort of pointless for that application, for super tight short track racing sure, MAYBE a hard tail 26 inch bike.
In my experience, almost 100% of the triathletes I know, get a MTB, use it for Xterra and endurance racing. I think a 29er is awesome because very few of these courses are truly super technical and lots of them take you on dirt roads and through sand, 29er is perfect for that, but I ride pretty technical stuff all the time on my 29er and have no problems. maybe its not the best bike for everybody but Viggen, coming from an “all mountain” rider, slander of the 29er is pretty meaningless.
I have never known anybody to get a 29er and go back to 26…regardless of height (another myth…that 29er is for tall people).
29er is where it is at. the 26 hardtail is a thing of the past.
I agree that you cant get as many tires for a 29er as a 26, but it is getting better, besides, you got the nevegal, small block 8, racing ralph, saguarro, mountain king, fast freddy, and a few maxxis tires to pick from, what else do you need??
I guess my point is this, free riding, all mountain downhill etc is what skiers and snowboarders do in the winter, not what the typical triathlete does as cross training. You have to ask yourself: since I am just going to have one MTB, do I want one I can use for actual training and endurance racing???..or am I trying to shred steep stuff and be at a loss when it comes to climbing and all day riding.
FWIW: if I had it my way…I would have a full suspension 29er, Niner Jet 9.
