I have a trek 7300fx. it appears to be an 05 model with disc brakes. this may or may not be useful information, because i got the bike used and the wheel set may be aftermarket. the rim's are wtb speed discs, if that aids in identification, and the brakes are hayes mx2's (i know, i hear they are garbage. but i'm not made of money here...). i was taking the hub apart to repack it and my balls all fell to the floor. now i dont know how many are supposed to go in each side. I managed to collect 24 of them, 12 on each side. but when i put 12 in there, theres a gap. as if there's supposed to be 13 on a given side. but when i put in the 13th ball, it doesnt quite fit. Now i'm rather at a loss. i'm going to my lbs tomorrow to buy all new bearings. but how many should i get? how many will fit in there? and what's with the gap?
thank you for your time
