Help! 1985 Fuji Mt. Fuji Ltd. Bottom bracket

[Monarkman]

Sorry to be a nerd here but . ... when I worked in a bike store years ago, a sage old dude with a big long beard told me the difference between spindles and axles.

He said , " Spindles spin!" . .. so an axle is something in the middle of an assembly where everything rotates around it (like in a hub) and a spindle is the part of the assembly that isolates rotational movement to what is attached to it (like in a lathe).

Thanks for listening to me vent. Now I have to attach a drive shaft to my rear axle and connect it to my crank and BB spindle.

Difference Between Spindle, Shaft and Axle?

Sure, let's break down the differences between these three mechanical components: Shaft, Spindle, and Axle. A ShaftA shaft is a rotating machine element,

btw Monarkman if you are using the original crankset on that Fuji, I would guess using a 68 x 122 or 127mm JIS taper 1.37" diameter x 26 thread per inch. I could be more helpful if you spec'd out which crank you are using.

Cheers

Well I’m an idiot and I think you are correct. The

well I’m a fool and I believe you are correct. I tried fitting a sakae triple ring on the 113 to see if it cleared, it did, however I recieved the Sugino AG and it did not, the end of the sprocket bolts would hit the frame.

I did some math and using my calipers I think the 122 will work.

It’s coming next week. I will post an update if it ever goes together, lol!

Thank you again for your knowledge and advice, I appreciate you and this community very much!
