Get a fork man , you can get cheaper forks that performe better then argyles and lighter too like a velour or a velvet for a fox imo I think argyles are over rated
Well the new ones are dec I love my velours and they weigh 3.85 with 10 inch steer tube there nice and light but don't get holy rollers there so heavy I'd say new seat and a pair of dth or rythm lites u will save lots of wieght
get some khe tires and a shadow piviotal seat or something nice and some high rise wide bars like ns or dobermans are nice too... bmx cranks like profile and premo are sick and light but thoes are fine.
