Hi.
I have an old, very well functional Kalkhoff Pro Connect 2011. However, now I have to replace the bearings for the headset/stem - they were broken and rusty. It is an integrated type, and I suspect it to be an IS41 type (SHIS) - Integrated-angular contact, 1-1/8 inch steering column, 36 x 45 degree contact “IS” or “Cane Creek® types. It appears to have a height of about 7mm.

Does anyone know a compatible bearing I can purchase that might fit?

Images for the stem is here

Cheers
