TOP FRAME RACE CUP 47-54
Top steering head race cup for the 47-54 frame range, also known by its earlier part number G88B.
This is the top steering head race cup, the fitting that seats the upper bearing race where the steering stem passes through the frame's headstock. Catalog notes tie this one to the 47-54 range, so it belongs to the earlier end of the pre-unit era rather than the later frames. The legacy number for this part is G88B, which is the letter-prefix form you'll see in older parts books alongside the current 97-0437.

The cup is a small but important piece of the steering assembly — it's the hard surface the bearing balls or rollers ride against, pressed into the frame's headstock. If it's worn, pitted, or loose in its seat, steering feel goes vague and the head bearings won't preload properly no matter how you adjust them.
We don't have much more detail on file for this one beyond the catalog listing itself. If you're restoring a headstock assembly from this period, give us a call and we'll confirm it's the right cup for your frame before you order.
