Was too good to be true.
The upper cup doesn't fit in my head tube. Several mm too large in diameter.
I guess it might fit in the aluminum version of the frame. Kinda makes me wonder if it fits any carbon santa Cruz frames...
Can you elaborate? It doesn't seem like an IS41 upper cup can be off by several mm.
Looking at 9.8 schematics and it seems like it should be a simple drop in fit. Do the SC carbon head tubes taper internally such that the threaded portion of the upper cup doesn't just drop in? IS41 should be IS41...
Yes, that's correct. The threaded portion doesn't fit inside the head tube. The ID of the upper "bearing race" as it is formed into the frame is much smaller than the OD of the threaded portion of the upper cup.
