what do i need to know about forks n shocks before i spend money on a bike?
(kid's out on bike 3 or 4 times a week- usual trails for now- ballinastoe ticknock and sometimes bits of carrick...the shocks he has on his bike haven't lasted a year)
a decent set should last a year? longer? then i think there's different ways they're made up? that's prob what i need the info about. what's best for him chuckin the bike round usual trails?

...while i'm at it-is there much to know about gears n disc brakes?
i'd appreciate any advice-messages or posts. dervla
