If you havnt noticed they have no hills to ride so they ride what they've got they don't complain. Also yeah as you mentioned you had 15 years they are only 16 years old. No offence but I think its kinda sad ripping on kids who could show you up in the dj scene. But as much as I think your a sick freerider your like double their age and knowing these guys if they had access to a mountian and full suspension bike they would shred it up
