Pas sensor question.

[Wayners]

When I looked at a kit online I seen it with an option to order a left side or right size pas sensor with big hole.
I have no idea what I should order?
Thanks

You need to post more information about the bike and the kit. It depends on various details. I guess that left side would generally be easiest, but safest to post the details and see what people suggest.

So its normal for left side.
I think my current setup is left.
I'm still building the bike. Was a second hand wisper step through frame and some original bits.

One would say that most cadence PAS are fitted on the RHS behind the chain ring, however it matters not really whether fitted LHS or RHS.
RHS is a stealthier neater fit imv.
Personally I always fit behind the chain ring.

The PAS disc with a large central hole is for a Shimnao Hollowtech or a similar Sram bb which utilises outer bearings.

If your bike has a a traditional sq taper or Isis BB then one needs a disc with the small inner hole with splines .

You need to show a picture of the bottom bracket from underneath (turn the bike upside down). That shows everything from the chainwheel to the left side pedal arm, and another from the left side at an angle that shows the bottom bracket so that we can see what type of BB you have. Finally, you need to provide a link to the kit you want to buy so that we can see what type of pedal sensor they're offering.

Ok. I'll pick this up when I get that far.
I've got frame. Forks. Front wheel. Derailleur. That's it so far. Waiting for better weather so I can build it outside. Not much room in garage
