Folks are increasingly coming to us looking specifically for 29er mountain bikes, and in the last couple of years we've begun to stock more 29er options (and as always we can special order anything in from our manufacturers and distributors), but the debate between 26 and 29 inch rages on. For the record we don't think there's a 'wrong' choice, and whatever makes you happy and gets you out riding is good by us, but there was something of a milestone met last weekend when a 29er won its first World Cup Race (see article here).
We don't happen to carry the bike featured in the article, but we carry 29ers from Niner, Surly, Cannondale, Giant, Trek/Gary Fisher, and more. Just thought you should know.
