Which PAS sensor for octalink?

[blu joe]

I have a trek fx 7.5 that i electrified with a 17 amp KT controller and front hub motor. I am having difficulties getting the correct pas that will fit and work, which model pas sensor do i need?

 

[blu joe]

My bottom bracket is an octalink, maybe hollotech as i removed the crank arm before and could see right through the bottom bracket, bike is trek 7.5 fx with standard bottom bracket (pics attached in my posts)

If your crank is 16-17mm in diameter the cheapest type should be ok,
This type will fit a standard bottom bracket and can be fitted either side.

NOT recommended sellers just google links with pictures

Octalink cranks are wider than the standard square taper, i believe.

I can't offer direct experience, but when I Google pas sensor octalink I think there is enough there to find the answer, including a list of previous threads on here, and products specifically mentioning hollowtech, and known supplier names such as psppower.

Octalink or Hollowtech ?
One will need a differing type of PAS to fit each BB.

Hollowtech or the similar sram gxp type will need a BZ10C type PAS , octalink will need a PAS as indicated in #3.

The difference being the BZ10C PAS ring has the over sized inner diameter to go over the outer bearing casing.
