Superstar have cheap 45x45 ones but I need a 36x45 for an integrated tapered headtube (lower bearing).
1 1/8 inch ones are easy to source (SS, ebay etc.) but the 1.5 ones seem harder to find.
I've found this which I suspect is the right version
and this which is quite expensive £27 for stainless
Any suppliers that you know of...
