its horses for courses... People were thinking "the xx" bike is THE best size".. Till they hit something that size wasnt meant for... Steep tight-- ugly twisty jumpy trails--- 26" is your friend... Long flowy progressive XC hammer fest type trails--- 29" is your choice.. People are starting to realize its not the bike-- but rather the right bike for the right trail that matters...
When i ride my 26er HT I think about how much better it would be if I were on a 29er HT.
When I ride my 26 FS I think "ooo this is really great".
So i have come to this conclusion for my riding:
650B for FS
29er for HT
I think that would be a really great balance.....now i just need the money ha ha.
I like the 29ers just fine but still prefer my 26er. Seems more nimble in tight areas. It all depends on what you enjoy and what youre riding. Dont let fads influence your decision. Explore your options and make your own decision.
