I just looked it up for you and found that the recommended bearings are what I expected, completely standard, 41/28.6 for the top and 52/40 for the bottom. those measurements are inner and outer diameter. You can find those on Amazon or ebay easily. Just specify the Cane Creek Series 40 bearings for a good quality replacement. They are not angular contact, but as I said above, I think that is just BS.
First, thanks for the help.
Strange to me that the Cane Creek tool doesn't list ACB for this bike. I've found a few other posts with the same issue and they all mention ACB bearings, here's one I just found on chain reaction cycles' site about my specific model of bike-
I'm looking to replace the FSA lower bearing in my integrated headset (Trek Madone 3.1 H2 C 2013). The markings on the outer are:
TH industries 1.5" ACB 36* x 36*.
I can find lots that read 36* x 45* and 45* x 45*, but none that read 36* x 36*.
on Hope Tapered Headset Cartridge Bearing
Answer:
This bearing has dimensions of 52x40x7mm and has 45x45 angular contact.
The bearing required is manufactured by FSA; currently we do not have it in stock as it quite a specific bearing. However the FSA part number is:
160-6751
Guess I just need to track down that FSA part number, and find the matching upper cartridge as well. Hopefully the inner wall of my seized bearing comes off the fork crown without too much grief.
