Hey there, I have a mountain bike for 5 years, but after those 2 years, i changed to a new professional one with hydraulic brakes and 28 accelerations! it's green and has black springs pictures: http://imgur.com/a/PnrVB if you have a mountain bike too: Post a picture of it! Btw I come from the Netherlands and we don't have mountains so I'm a cheater but I do cycle on the higher grounds
