Need a bit help recently purchased rear hub kit all installed went to fit the pas sensor and the diameter of the hole on the sensor goes nowhere near the diameter of the crank will I need to change the crank to suit the sensor
Shouldn't need to.
The sensor ring fits behind the BB tightening ring or external bearing cone, one will need a crank remover and BB spanner to fit it in place.#
Best to post pics of the bike crank/BB and the PAS you have for a better understanding of the issue.
That PAS sensor looks like KT V12L dual hall type and should go on the non drive side, also it is for square taper axles. Yours BB looks like a isis BB so it isn't compatible, the cheapest option is to use a KT BZ10c type to piece PAS or adapt a std to piece magnet disc if you have a spare PAS set up.
Cheers I'll probably change the crank to suit then if I enjoy it again I'll look to upgrade the bike I'm getting on a bit and the knees aren't what they used to be so I thought this kit will help if not I haven't lost much
