When my IOLO got robbed last summer, I borrowed my mates bike (my old echo control) and after one ride, I couldn't walk due to smashing my thighs on the bars. Well random, 'cause it wasn't that much different. Yeah Joe, I'd also go with the recommendation for narrower bars. I'm running my Zoo's 2.5" narrower than normal, it should mean you're not leaning forward so much. It's mainly down to technique, so try just.. not hitting the bars. Oh, and you're not growing, don't be silly lil' Joe.
