I have a Torrot with a Zeus BB. I've checked the cups with a pitch gauge and they fit in the metric system part in the 1mm gauge so they are 35mm x 1 mm. The funny part is that the fixed cup is left-handed. This means I have an spanish bike with a suisse BB? I´ve been digging in old Zeus catalogues and it seems Zeus did french, british ans italian standards but not suisse. Any idea? This really wierd or I´m missing something?
