Headset Bearings.

ara3791

I need to replace the headset bearings on my 2011 Argon 18 Radon, "first time".

Looking at the tech sheet for my Radon the headset is: FSA Orbit IS-1, ( 1’’-1/8 bearings, 15mm top cap, 36 /45 )

Will the following in 36/45 fit?

If not, please recommend a source.

Thanks in advance.

the 36/45 Nukeproof is the lower bearing in a tapered pair, so 1.5" not 1 1/8.

Superstar sells cheap ones. They are fine and cheap enough to replace whenever.

Just check the outer diameter of your existing bearings is 41mm. Some bearing units are 41.8, although they tend to be the 45/45 type IIRC.

Not all 36/45 bearings are exactly the same, they can be different heights, and the imagine filing in the angles of 36 and 45, you could file more or less away at the same angle. I know that doesn't help much, but you will need to get the right ones.

if you have the fsa tech sheet for the headset, doesn't it state the standard bearing code? for instance 873-2RS

once you have that code, you can just go search for that
