Re the YST Threadless BB
By Xav
15 Aug 2024
Hello,
I installed the YST Threadless BB to correct Nm, but on the 1st test run, it came loose. On the 2nd test run, I used plumbers tape, but it still failed to stay in place. On the 3rd test run, I used loctite threadlocker (blue 248), but it still worked itself loose. I'm thinking of trying red 268, but if it works, I won't be able to remove it if there's a problem. If it doesn't work, do you sell an alternative?

I would get a local bike shop to check and clean the threads, it could be the shell is damaged. SK 21/08/24

Re the YST Threadless Repair Bottom Bracket - Square Taper. Can you advise how to select the correct measurement option on you web page. The width of my bottom bracket on the frame is 68mm.
SJS Customer Service:
You need to measure the end to end of the axle of your existing BB and purchase a new of one the same length. You will also need to measure the diameter of the hub shell and make sure this corresponds with this BB. We would recommend taking your bike to a professional cycle mechanic for further assistance in BB identification.

None apart from where we buy them and the branding, we keep both in case there is a supply issue RT
68 cartridge in a 73mm shell
By Anonymous
01 Mar 2020
Hi, is there a reasonable amount of thread on this, enough that I could tighten a decent number of turns with 5mm still to go? It seems impossible to buy repair cartridges with a 73mm body and I'd prefer not to pay to get the frame reduced and faced ...
SJS Customer Service:
The axle would be "lost" inside the LH cup, so this would not work. You need a 73mm for 73mm shells.

Use with vintage Raleigh 70-71 mm bracket shell?
By Anonymous
02 Dec 2019
This 68mm YTS BB is similar to the 68mm Velo Orange, which is reported to work satisfactorily in a 71mm Raleigh shell. Will the YTS also fit the Raleigh? Any downsides to the YTS? Will filling or chamfering the shell (for a better fit) render the threads unusable in future?
SJS Customer Service:
Hi there,
Unfortunately, we can only guarantee that this will work with a 68mm shell I'm afraid. As we have never tried this with your bike we cannot say for certain whether it would work or not I'm afraid.
Thanks.

spindle length
By Marc

Am currently using a Oxford cycles thread-less bracket which has developed spindle play after less than 2000 miles (bracket still snug). Also I am having a bit of trouble getting my front derailler far enough out (it touches the chain on the two smallest rear cogs. It has a 113mm spindle length. (Shimano FC-m410 crankset) Shimano seems to be recommending a 113mm spindle but would 110mm or less not be better?
SJS Customer Service:
Hi,
Shimano do indeed recommend a 113mm spindle, however, in your situation it does sound as though a shorter spindle would be beneficial.
Thanks.

Can I use this in a BB shell with a 38mm diameter?
By José Miguel Mendes

I am refurbishing a Gazelle Tour de France which has a threadless 38mm diameter shell. Does this BB fit that shell?
SJS Customer Service:
Hi there,
Unfortunately the Diameter of the bottom bracket is 34mm so is too small.
Thanks.

Frame preparation?
By Newly

Does this BB require any frame preparation?
SJS Customer Service:
Hi,
If your frame has never had the BB shell faced then this may be required to get a tight enough fit but otherwise no additional frame prep should be required.
Thanks.
