Hi, I'm new here, thanks for advance for any advice. I'm currently restoring this lo pro which came with a Mavic Challenger rear wheel.
Does anyone have any experience of servicing these? It runs smooth but I know it's been in a shed since 1991! It looks like has circlips holding the retaining nuts in place?
The cassette is a 7 speed suntour screw on type.
I can't find anything despite trawling the internet.
