Headset bearings MH-PO3M
I have a 2009 Felt Z35 with a VP-A61ACK headset. Although the largest logo on the headset says Cane Creek it is definitely not a Cane Creek model. The bearings however are clearly marked MH-PO3M. I cannot find on-line any where to buy these bearing or any information on the internal/external angles of this bearing. Are they 36/45 degrees or 45/45 degrees? The VP website is no help.
Have emailed VP, the manufacturer, but no reply to date! Help please.
Thanks.

Try Simply Bearings web site. Search with MHP03 (zero three). I have used these. I do not know the relevance of the last "M". Mine were also marked (0 41*6.5*45*).0

You need 41x6.5x36x45 bearings, any with these specifications will work. (Cane Creek standard)0

Thanks to you both for replying. Unfortunately you contradict one another as the MH-PO3 is angled at 45/45 degrees.
It is verification in a tech spec that I really need if not to damage my headset.0 -
Measure the external diameter of the bearings.
41 mm is CaneCreek standard 45x36, appr. 42 mm is Campagnolo standard 45x45
(I assume its full integrated, semi integrated is a different story)0 -
Ignore my post. I was too quick to give you advise. Having looked a bit deeper into this, I think I could have the wrong bearings in but they seem to work ok! :oops:0

Sorry Keezx, not as simple as that! If you look at airebearings website the HM-PO3 is 30.15mm ID, 41mm OD and 6.5mm thick with 45/45 degree angles and the HM-PO3K has identical ID,OD and thickness but 36/45 degree angles! So a dead end there I think for me
However after much trawling through on the internet found http://www.vpcomponents.com/tw/book/index.php?id=5
which solved the problem. So an HM-PO3 appears to be the answer.0 -
Apparently some manufacturers have made their own versions of the "standards".
They should be punished heavily for that......0 -
Agreed, but knowledge is power.
