NO its good, i rode the '09 Yeti and its the only DJ bike that i can truly say i loved the most. I got the 2010 one at a V.V. Good price. It weighs the same as last years, but has adjustable dropouts, tapered headtube and is a lot lot stronger
it isnt just weight difference that should define a good frame guys, yeti spent AGES designing and testing the geo, the tube shape size and thickness the adjustable/replaceable dropouts, the headtube and they have refined it to this, weight isnt everything if the geo sucks and the yeti rides amazingly well and i have ridden lighter bikes that feel slugish in comparison, so bare that in mind when your looking at price and weight of frames.
the yeti dj can be used for dj thats why its called that, doesnt mean it cant be used for 4x and doesnt mean it has to be called 4x, you can get horizontal dropouts for it for 70 bucks anyway . . .
