Item Condition
I grade products as honestly as possible and depict blemishes in both description and photos—please study them carefully. I tend to be overcritical and customers report items to be in better shape than expected often. From best condition to worst condition, my grading scale is as follows. Mint / near mint+ / near mint / excellent+ / excellent / great / very good / average / fair.

Description
Description
This lightweight bb is fully rebuildable! It features roller bearings, and can be easily greased just by removing the cups. These are getting harder to find in good shape.
This is an Octalink V1 bb, and is compatible with Dura Ace 7700, Ultegra 6500, and 105 5500 series cranks, as well as other manufacturer's cranks that use Octalink V1 (FSA, Ritchey, etc). It is NOT compatible with Deore, Tiagra, Sora cranks, which use Octalink V2 BB-ES51 bottom brackets (available below)
Condition:
Great used shape. Bearings are freshly greased, and spin smoothly with zero play. You can feel a bit of grit every now and then. Some light tool damage on a couple of the notches. Cups look great.
Details:
- Spindle length: 109.5mm (for double cranks)
- Threads: English 68mm shell, 1.37x24
- Octalink V1

I'm always buying high end bikes, parts, accessories, memorabilia, etc. While I'm particularly seeking large piles of new old stock parts, used items in nice condition are welcome.
