Bottom Bracket fit/montage
By

Hi,
first of all on the picture it says 73 mm, in the description it says 68 mm tho, so whats the actual width?
I have a damaged bottom bracket with a diameter of 34 mm and a width of 67 mm, will the listed bracket fit my frame?
and the final question is, if the frame really doesn't require any preparations?
Hi,

We have just used the same image for all 3 sizes so this is definitely the 68mm option and will be a suitable replacement in the frame you have described. Aside from removing the any paint on the external faces of the bottom bracket shell no additional frame prep is required.

Thanks.
My Damaged Bottom Bracket Replacement

My damaged bottom bracket is a Nervex and is 66mm. The YST bottom bracket I bought does not tighten up enough will your one go down this far and/ or do you sell spacers?

Thanks
Hi,

As this bottom bracket is designed around a 68mm shell it is unlikely you'll be able to tighten it up enough for a 66mm shell width. However we do stock some spacers that should help, these are SJSC part number 27247.

Thanks.
Damaged The Threads In My Frame ..

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 ?
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.
Will It Work With Spacers If The Bb Shell Is 65Mm

Hi,

Although this isn't something we have ever tried, it should be okay for use with a small amount of spacers.

Thanks.
Hi, Is The Bb Jis Or Iso Standard?

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.
Hi,

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

Thanks.
