So I have a pake bike that I got off of a craigslist guy. Tore it all down and this is the bottom bracket that came out.

Truvativ.............BB-06-sq-le-108/68

I am currently shopping for a new BB and I am not sure what exactly I have...as in are they english threads? Italian threads? Or what?

I am trying to understand what I have and what I can use as a replacement and I need some guidance.

I assume all the info is in the part number, but I am not sure how to decipher it.

Thanks

Its english threaded BB that is 68 (diameter) x 108 (length) based on the PN of what you pulled out. SQ stands for a square taper and LE is the model of BB produced by Truvativ. No idea what the 06 stands for but you can buy this same BB new for $21 from Amazon

And for what it's worth, any 68x108 bb should work, you don't necessarily need to stick with a Truvativ.

No cigar Unkle Sparky.

Oh, well thats what i always thought that number meant. Care to share Squidbutt

Shell WIDTH. The diameter is only about 42mm.

Squid butt ..... :

It takes 68 turns total to secure both cups of the BB, right?

Anybody want to chime in with whether it is ISO or JIS?

Well ballz. I guess i have no idea what i'm talking about then

You're sure it's not this one?https://www.amazon.com/bottom-Bracket.../dp/B002LYLS04

At any rate, that says JIS.

Edit: that has 113mms spindle so it isn't the same.

I deleted my previous post because a quick look in my Truvativ catalog shows that particular BB to have a 108mm JIS spindle, not Powerspline as I had originally suspected.

What is it that tells you the what kind of threads it has?

Also, I am looking for a "high end" bottom bracket, not an exact replacement. Are Miche bottom brackets any good?

Like this one...

Your Pake frame has a 68mm English-threaded shell. You will need an English-threaded BB.

Damn... missed my chance to snarkily correct your correction of me
