Will this damage the threads In my vintage steel frame.

By Duncan Gould

11 May 2020

The threads are actually still in excellent condition but there is some slight misalignment when the threads were originally cut which makes fitting a conventional sealed cartridge bracket difficult. There is also a residual stress on the cartridge as a result which is not helpful for a long life. This could be a solution, or reverting to the old cup and cone system?

SJS Customer Service:

Hi, this can be fitted to a threaded bottom bracket and it is a great solution for damaged threads. I can not say if it will or will not cause damage to your good threads. Thanks

This Threadless Bottom Bracket In Loose Thread For Bottom Bracket

By Martin Riis Sønnichsen

28 Mar 2016

I have an old trek oclv with a loose thread for the bottom bracket. Will this threadless bottom bracket maybe be the solution? And if so: which length/width of axel will I need? I will use a single speed setup. Kind regards Martin Riis Sønnichsen

SJS Customer Service:

Hi,

A threadless option should solve your issue. As we don't sell you bike and have never had one here there is no way for us to know what specification of bottom bracket was originally fitted, you will need to see what size your current bottom bracket is and match the dimensions of that to one of the threadless options.

Thanks.

Does This Fot Italian Bottom Bracket Cups?

SJS Customer Service:

Hi,

Italian type bottom brackets were produced around a 70mm shell, this is only 68mm so I would recommend sticking to one that is 70mm like SJSC part number 32373.

Thanks.
