Headset bearing on Planet X RT-58

[JaAnTr]

Hi,

Today I took my forks off as the steering was becoming incredibly stiff. I had an absolute nightmare getting the headset bearing off, it took being hit probably over 100 times before it finally came off. Once I cleaned and regreased everything I assumed it would go back on easily but it's just won't budge. I can only assume that it's somehow shrunk because it is incredibly tight and I don't have anyway to hit it back on.

So I'm looking to buy a new one but have no idea what to buy or what size. Is it just something like this - http://www.wiggle.co.uk/cane-creek-headset-bearing/

And how will I know if it fits?

Thanks!

Degrease it and the sizes should be etched on the bearings.

I also won't budge if you hit me 100 times.

What part of the headset was struck? Where was it struck and what part has now deformed?

It may come in handy to know that this exists.About 1/3 the price of the FSA equivalent which is fitted in my carbon RT58. Does the alloy version have a 1 1/2 1 1/8 headtube?

I worked through this problem last night for my Roubaix, there seems to be an incredible number of variations in sizes even within on size like 1 5/8". In the end used a digital calliper to measure the internal, out diameters and the thickness then found the bearing from these guys. Watch is there an chamfer on the external or internal faces? http://www.edgesportsuk.com/store/components.html?cat=32

When I received my RT58 the build sheet had the headset specification they had used on it, I had trouble finding a compatible one with correct angles and ended up purchaseing same one from Planet X.

That's good to know, I have the Carbon RT 58 so I've just bought one! Thanks.

I`ve bought one too but in the light of what @Roger posted I`ll be checking bearing contact angles and what not.
