SJS always provide value for money but this item ticked all the boxes. As previous reviewer says it works perfectly and I dread to think what it would cost to repair the BB threads - if that was indeed possible - had not this piece of kit come to my rescue
Good Quality Bb That Saves A Bike From The Scrapyard!

ConsNeed two BB tools to get a tight fit.
ProsSaves an old frame from expensive new bottom bracket retooling, or going to the skip!
This is a great piece of kit, that does what it's supposed to do. I had one of these (but a cheaper model) for 5 years in an old mountain bike, never had a problem with it. Just replaced it, as it was getting some rust and had a small amount of play, with this, more expensive version. Easy to fit - you need two bottom bracket tools, as it screws into itself, so clamping tight into the frame - you need the two tools to get it really tight. Good quality, smooth bearings.

Spindle Width/Length

Is there a 103mm option my frame is a 2009 specialized Langster chain line is 42mm

This bottom bracket is not available in that width but we stock a different threadless one in 68mm and 103mm length. These are SJSC part 35532.

I currently have a Shimano UN55 BB, 68mm x 118mm.

My BB frame threads are worn so the BB moves around when pedalling.

Will this 68mm x 119mm be a suitable upgrade ? Does the additional 1mm length have much effect on chain alignment ?

This would be a suitable replacement option if you're threads have been stripped. The 1mm difference should not make a noticeable difference to your chainline.

Is It Possible To Add A 2,5 Mm Spacer To Improve The Chain Line?
11 Sep 2016
This 127,5 mm BB has to replace a 136 mm BB. Can I add a 2,5 mm spacer at the drive side to improve the chain line?



This bottom has an angled edge so it is unlikely to sit well with a spacer, if you can get a spacer to fit well then you should be okay to fit a small spacer up to 2.5mm in size.

Is This Unit Comparable With The Dotek 42T Single?
14 May 2015
Is this unite compatable with the Dotek 42T chainset? If not please could you recommend a suitable pairing? Cheers Patrick

Providing you select the 113mm length recommended for the Dotek chainset then yes this will be compatible.
