First upgrade SJ 120
I'd like to up grade some parts my '05 SJ 120. I ride xc, weigh 220 lbs. I like to do small drops 2-3 feet. I'm looking to lighten up the bike some. What upgrades would you recommend considering my weight.
XT cranks w/ external BB
a good wheelset (i ride Mavic CrossMax XL and i am 205lbs) can lighten the ride.
the stock tires are good and if you do drops and stuff you don't want to go much smaller than them, i ride 2.4" tires which are heavier.

just like a speeder-bike
My 1st upgrade to my 120 Pro was Crank Bros Eggbeaters -- nice 'n light.

Fork - replaced the minute with a Talas RLC (it rocks!)
Brakes and shifters - returned the shimano integrated pieces of garbage and got xt rapid fire and juicy 7's. Also put a 7" rotor up front.
