So I have started to piece some things together.

I have or have ordered these parts:
SRAM x-7 9 speed (although the product says 10) rear derailleur

SRAM X Gen Front Derailleur 9 speed

Im still not sure if there is a particular cassette I should order. I dont know much about the differences except for the gearing. I am also unsure about what 9 speed chain to order and if there are particular cables that would be recommended for a build of my style.

Also I have some standard v-brakes on the bike. I was going to upgrade these to a disc setup at the same time, maybe some avid mechanicals but I spaced it and didnt think that I wouldnt have the hubs to support them. So I plan on upgrading all the drive line stuff and either putting new replacement v-brakes on or waiting till I have the money for a new wheelset and disc brakes

Do my plans sound like I am heading in the right direction? If not please make some suggestions and help me select better parts. Thanks!
