Can someone tell me the count please?

David

I don't think any of the '84 Mongoose models came with 3-piece cranks, at least according to the '84 catalog at vintagemongoose.com.

THATS why I couldnt figure it out.
Basically I was looking to replace the BB bearings/hardware, and all the ones I saw had a spline count, but my cranks dont have splines.
Thanks for straightening me out and please forgive my ignorance.

You should be able to use just about any one-piece (24tpi) bottom bracket on your Mongoose.

agreed.
i think by 1984 they were using all 24tpi (earlier Mongoose 1-pc cranks were 28tpi).

So, you guys are pretty sure '84 had the 24 tpi? I am gonna order this one if so, unless someone has a better suggestion.

Hi David,

Not sure if I understand your situation. If you have the one-piece cranks, measure how many threads per inch. Or you can measure 1/2" and multiply by two. That will tell you if you need 24 or 28 TPI.

For axample, if you measure 12 threads in 1/2", then you need a 24 TPI BB.

Hope this makes sense.

Yeah, I would have, but I dont have the cranks with me at this time, and was kinda on a roll with ordering new parts. You know how it is when you get excited and start spending money
I guess I could wait 'til I pick them up.
Thanks guys

My friend counted em, and he says its a 28.
