Bought this for use on a 1980's Raleigh racer. It fitted well and impressed with the quality. Would not hesitate to buy again.

ProsSolid, smooth

Perfect! Even got it mounted using just one BB tool by going from side to side, tightening just a little each time. 2 tool recommended though for easy mounting.

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.

You list this bb at 41.99, and another from YST for 16.99.

By STUART ANDERSON

You list this bb at 41.99, and another from YST for 16.99. The photo shows them to be exactly the same product. Is this a Sunlite product or a YST product?

SJS Customer Service:

Hello, they are both YST products- the difference in price comes from the quality of materials, bearings and tooling used during manufacture.

Will this fit a 36mm shell?

By Anonymous

25 Aug 2018

I have an old manxman frame that has a 36mm inner shell BB diameter without threads, will this fit?

SJS Customer Service:

Hi there,

The approximate shell size is 34mm, so it would be slightly too small.

Thanks.

what's the difference to YST product ?

By Anonymous

You list this bearing at £41.99, and another from YST for £16.99. The photos appear to show the same product.

So, what's different about the Sunlite product over the YST ?

(Experience of a YST is its OK for a year or so, then gets very noisy/draggy, which means chucking away again... )

SJS Customer Service:

Hi,

The bearings are different in the Sunlite unit, but otherwise the construction is basically the same. We get these from different suppliers and charge what they set as the RRP for them.

Thanks.

What size do I need for a Apollo disk 26 bike?

By Anthony Eaves

17 Aug 2017

Hi I have a Apollo disk 26 but not sure what length I need any help would be appreciated thanks

SJS Customer Service:

Hi,

The length would depend on what cranks you have got fitted, the easiest way to check though would be to just remove the cranks and measure the length of the old one.

Thanks.

Sizing

By Ian

21 Jan 2017

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 ?

SJS Customer Service:

Hi,

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.

Thanks.

Is It Possible To Add A 2,5 Mm Spacer To Improve The Chain Line?

By Bart

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?

Regards

Bart

SJS Customer Service:

Hi,

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.

Thanks.

Is this unite compatable with the Dotek 42T chainset? If not please could you recommend a suitable pairing? Cheers Patrick

SJS Customer Service:

Hi,

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

Thanks.
