Hi , with a bit of luck ("Sheffield") I might have a Mavic 616 cartridge BB in my hands soon. Sounds like the bearings are not good. Is it possible to get replacements and fit them yourself, I would think its a certain tool, but are they standard bearings and easily(cheaply) available?

Cheers Darren

Hi Darren,

There's a technical sheet in the Gallery.
On page 2 it seems that the cups slide off the axle, cassette bearings press fitted onto the axle. Nothing too weird.

Also:

The bearings themselves are given Mavic part numbers, but are 16x30x9mm apparently, not standard 6902 (15x28x7mm) or 6903 (30x17x7mm).

SKF number SKF part # BB1-3507: (stolen pic from Flickr)

A quick look on the SKF Bearing finder ironically found nothing...doesn't look good for replacements :(

I've got the BB cutter if you need :D

All the best,

Many thanks Dan for taking the time to find this, I'll wait and see what it's like when I get it, the mechanics are easy but I'm guessing it could be tricky to find.
Cheers Darren
