Orbea rise m20 headset bearings

[Rod B.]

Thanks for your detailed reply as always Rod. Luckily I solved the problem the same afternoon I posted that, all documented above ^

It was brand new bearings I was fitting. I’d forgotten to remove the rubber insert from the old bearings that sits on top of the upper bearings so without that installed I was getting that slight rocking sensation when testing with the front brake on.

It’ll bite you on the ass every time….

The complete spec for the lower bearing (Orbea Rise M20 2021) is 40x52x7 mm - 45x45 deg
I was not able to source a stainless steel version in Norway, got mine from kulelager24.no after 3 days.
I believe the bearing is semi-integrated?
Below is a picture showing the geometry

AliExpress sells the bearings (MH-P16) for as low as US $ 3.12 (+VAT and shipping if applicable).
They are obviously not stainless, but with the low price I can buy a set of 6 (free shipping) for the same cost as the one I bought in Norway (also not stainless), and replace as required!
