If you're a guy, you better be bloody good to pull that off, otherwise it just looks like you're trying to hard. I seen a kid on a similar coloured bike (plus pink tires) at glentress, he was hitting the top of the wallrides so got away with it!
My mates son (15yo) was getting slagged off by some guy at Innerleithen for having a pink 224. He asked the guy to try and keep up with him on the way down. He couldnt and when the guy got to the bottom the wee man just shook his head, said 'mincer' and cycled away. Quality!!!
