    Bearing sizes

    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!

    '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

    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.
