Great solution to damaged b b threads

I recommend this product

ConsNeeds two splined tools to install securely

ProsPermanent work-around for damaged bottom bracket threads

I have been running one of these for years/miles - bought this as a spare/replacement as previous bearings are starting to show their age.
Great product - I took some care in ensuring correct fit in the bottom bracket tube, and once torqued into the frame, has been a solid fit.

Hello, we cannot say as we have not stocked Klein press-fit bearings to make a comparison.

Is it 73x116 or 68x116?

By Simson

03 May 2020

I need a 73mm wide bottom bracket (shell). In the title it says 68mm, but I see in the picture of the 116 wide axle, that it says 73x116.
Is the 116 size 73 or 68 wide?
Thank you (=

SJS Customer Service:

Hi, they are 68 mm. We will change the picture. Thanks

Torque

How much torque should I dial in to my wrench when fitting these? I couldn't find any guidance in the packaging.

SJS Customer Service:

We recommend 35-45Nm.

Damaged The Threads In My Frame ..

By Nigel Prior

27 Mar 2017

Hi. I have damaged the threads in my frame so the new Shimano UN55 Square Taper Bottom Bracket Silver, 68 x 118mm, English Thread, I have purchased wont fit. This looks like the perfect solution so I do not need to purchase a new frame. Which size do I need to order ?

SJS Customer Service:

Hi,

As we don't have an exact 118mm replacement option we would recommend going for the next nearest at 119mm. This should not affect the chainline by a noticeable amount so should not cause any issues.

Thanks.

Diameter Of Your "Threadless 68 Mm Sealed Bearing Bottom Bracket For Frames With Damaged Threads"

By Nicholas Frankau

18 Oct 2013

Will this fit a 34mm diameter (68mm wide) bottom bracket? If not do you sell a similar product that does ... or a 35mm x 68mm bottom bracket which would work if I had my frame rethreaded. Many thanks.

SJS Customer Service:

Hi,

Yes this bottom bracket will fit fine as it fits your necessary dimensions.

Thanks.
