hay guys, i have a 2004 hardrock, and i just got Rear Derailleur: Shimano Deore LX SGS &
Front Derailleur: Shimano Deore LX, top-pull. i currently have a truvantive x-flow crank. so my problem is that i have a 7 speed & the derailleur is a 9 speed. can anyone tell if my front crank is compatible for the front derailleurs, and what Cassette Sprockets i can get for 9 spd conversion...my budget is $60 for everything including front crank if i need to change it
 
to convert to 9 speed you would also need new shifters, a whole new cassette, and a new chain. not at all economical.
