I hop back and forth between 26″ and 29″ wheeled bikes depending on mood and trails.
I hired a 27.5 trek ex7 on holiday for a day at mammoth.
I handed it back at the end of the day feeling a bit meh,
It was bloody hard work, it felt dead and needed manhandling round corners. Its stability issues at speed would have you thinking it should be nimble in corners- but once you slowed it down it cornered like my land rover.
In short wont be rushing out to buy one.
And in a blind taste test mrs t-r who is a very credible rider in her own right – but doesnt do technicals of bikes just rides em. Said the next day after a day on a 29er – that bike rides better than the one we had yesterday ( she has a 26″ wheeled bike at home)
