Personally I feel both are classified as 'trail bike'. A 29er is said to feel like a 26er with an inch of travel so a 100mm 29er would be comparable to 26er 120mm in my opinion. It really all depends on how you set it up. 29er with travel a 'racerboy' bike, that's just silly in my opinion. Ride both. There both great bikes. Yeah, I'm that peep that's agreeing now! But only because I love arguing with Ray so much.
