- Manufactured by a well established British bearing supplier, these twin row caged roller bigends are made as per the original design (Like the International variety, I use them in my own bikes). - Fitted to Model 30M (Longstroke Manx type) and Pre 1962 (non-lipped) DOHC Shortstroke Manx's, these Bigends are narrower than International Bigend assemblies, which can be seen in the second photograph for comparison - Note: These Manx Bigend units are supplied without nuts. Earlier Manx Bigends (all SOHC\DOHC magnesium cased pre-featerhbed engines and earlier Featherbed engines) used large 47mm AF Hex Nuts. Later shortstroke DOHC engines used castellated nuts. I can supply both types. If you are not sure if your flywheels should be using Hex nuts - look for the 'Mickey Mouse ear' cutaways, for grub screws (see 3rd photograph), which signify it was fitted with Hex nuts. Wherever possible, if the engine was fitted with these larger nuts, you should try and refit them, as they provide a larger surface area than castellated or International nuts.
