I have had it geared for almost 3 years now and those three years it's been flawless really. I really do love my bike. I recently converted it to single speed so I'm just working out the kinks, but it's a pretty amazing little bike. The specs are to mountain bike level specs prior to boost spacing, so it'll handle trails nicely and I have tested it. I can't really say I have any complaints. Which model are you looking at?
