Can someone tell me what bearing sizes I need for:

Ultegra BB-6500 octalink
Ultegra 8-speed hubs, front and rear

Or a link where I can find that info.

Thanks!

The Ultegra Octalink bottom bracket is unservicable as it is a sealed unit. The only way I can see to get inside one is with a hacksaw or can opener. :)

The front hub uses 3/16" bearing balls, 10 balls per side.

The rear hub requires 1/4' bearing balls, 9 per side.
