Overall Product Rating 5 / 5

great product, saves frame

By Matt Egan

5 / 5

I recommend this product

ConsNeeds two cartridge tools.

ProsSaves frame, so super value for money

Fitted to a steel touring bike whose bb threads had rusted/worn away (puddles, winter roads, occasional beach trips etc take their toll even when the bb is removed regularly).

Tried various bodges using a normal cartridge. None of them lasted more than a month or so, and all of them failed 'suddenly', mid-ride.

This alternative fits fine - does not wobble within frame. So far so good after 1 month / 3-4 hundred miles.

Well designed

ProsEasy to tighten up -used thread lock

This is a much better design than the earlier version and seems to work very well.

Do you ask anything like this for 73mm BB's?

By Tim

I'm struggling to get my bottom bracket in my frame and think the threads may be damaged. Do you have 1 of these threadless bottom brackets to fit a 73mm housing? Looking for 122-127 mm in length.

SJS Customer Service:

Sadly we do not stock a BB for damaged threads in the 73mm size.

Can you supply / advise please ?

I have a partly stripped BB 68x113mm (the first 5mm on non-drive side) Can you supply a threadless BB and appropriate 170mm / 110 BDC cranks ? Would this fit in ok on the non-stripped side ? Thanks for any help or advice.

SJS Customer Service:

This is it, select 113mm

Can i use this in a brompton? i'm fed up of the plastic cups if not, do you have any other options?

SJS Customer Service:

You can, but its designed for frames with damaged threads, so We would soon recommend a Shimano UN55 118mm or anything else in 119mm. Otherwise a Ti Parts Workshop or Royce would be the top end choice.

Thanks
