A NOS pair of Sugino CV-SB sealed bearings and cups. These are slightly different to the other sealed bottom bracket bearings and cups and can be difficult to fine. Most used sets have beat up alloy cups too!
Cups are stamped with Sugino Japan Conversion Sealed Bearing CV-SB 51.35 and the bearings have NSK 41.3 6004DU Japan.
I think these were used on bottom brackets for the Sugino/Redline 400 cranks and also the Diamond Back Harry Leary Turbo cranks.
