All,
I have just acquired a '54 Hetchins from UK ebay. On stripping it for refurbishment, I find it has an Ofmega bottom bracket even though it has a Stronglight 99 crank. I have no idea of the timeline for these items, and have not been able to get any useable information from Google. It is English threaded, but has no provision for a lockring on the left side. Perhaps it is an early cartridge type? The outsides of the two cups are castellated, not slotted, so presumably there is a specific tool to remove these without resorting to the old Channelocks?? Can anybody forward any information?
Thanks
