I'm looking to replace the bearings in the headset on a brand new GT mountain Bike (they have disintegrated after 4 weeks).They were the caged type but exposed so I can see each of the balls in the ring (i.e. not sealed)
I know from Cane Creek site that I have ZS 44/28.6 & ZS44/30 sized headset but no clue what the relationship is to my bearing size....sorry if this is a silly question!
Can anyone please recommend where I can buy the bearings?
