Hi all. Lately my headset set has been stiff and making a crunching noise. So today I decided to try and give it a self service. As I was dismantling the headset I didnt realise the ball bearings just sat in the top with only a small lip around them and they proceeded to fall on the floor as I eased the top off. I have now lost about half of them. Can you just buy ball bearings and are they all the same size when it comes to headsets. The headset in question is a FSA NO.57E, E2, ACB sealed bearings
dont worry a lump of wood and a hammer will fix that
If they were loose ball bearings then yes - easily and cheaply available.
If they're sealed bearings, they should be held within the race and shouldn't come bouncing out. You need to remove the inner and outer races and examine them for a number (such as 6808-2RS) then replace the whole bearing.
Is this a tapered headset from a Trek? It might be worth calling your nearest Trek dealer to get replacements.
Yes its off a trek thanks for the help. I think they only bounced out cos I knocked the bike as I was pulling the top bit out
