Just purchased a 2011 hifi deluxe. love the bike, have a question on the tire sizes. it came with the Bontrager tires but the front tire size is 29x2.25 55/57 while the rear is 29x2.0 44/50 - much more narrow in the rear. The LBS stated this was normal stock. Seems a bit unusual, can't say i've seen this before (though i don't tend to stare at tire sizes on the trail). My specialize has like sizes front and back. anyone have a 2011 that is similar or different?
