Decoding the headset.

omri

So I have this headset on my bike and I need to replace it.

Headset 42/286-IS42/30 Orbit FSA 15mm Ahead.

So far I found fsa orbit cf carbon but im not sure if this one will fit. Based on these numbers is it possible to identify aby othe headsets that will fit?

I have all the tools i need to replace them myself - just wondering if removing cups from carbon frame is same as from non carbon just need to be done more carefully?

Also found these markings on the bearings:

th industries 1-1/8 45x45
no. 8b acb comp w campy

It seems I did manage to find the same model.

My question now - is there a better model to this one - or am I supposed to use just this very model on my bike ?

I still have the original headset on my Lapierre bike. Its 8 years old this year. I'm always surprised when i hear people saying they need a new headset. I have replaced the bottom bearing as it was noisy, but that's it in 8 years! (Bike does 8,000klm per year)

What am i doing wrong?

I'm sure mine is fine but a while ago I've seen some rubber peeling from inside of it - space between the cone on top and the cup. Not sure why it happend or is it a bad thing to happen or should I ignore it or what..

Post a photo?

It sounds like a rubber seal? If it is, I'd simply check the headset bearings every now and then, add some grease and leave it at that. This is something I do on an annual basis anyway.

Couldve been the seal from the cone that sealed the bearing from the top - I'm pretty sure it was in fact and as far as I can remember I just peeled it all off as it looked crap with bits sticking out. But it's been a while and I cant remember now exactly.
