hi... the other day i was riding on my bike and my rim become crap... then im thinking to buy a new rim... but my budget is limited so i have a 36 hole hub and i found a great rim on nashbar (a mavic f519 i guess)... and it has 36 hole... so the problem is that im planning in a future time to change mi drive train... currently i have 21 speeds and if want to upgrade i know i will need a new hub for 8 or 9 speed cassettes... but i cant find a place that sells a 36 hole hub anymore... what to do in this case? the deore hubs are made for 32 or even 28 but not for 36....
