Is cadence magnet necessary when installing SRM power meter?

Let me fix that for you:
Epoxy should be overkill?

Although this may not work for certain bottom bracket standards, for our BB86 and BB30 frames, I attach 5mm round flat magnet to the chain stay directly behind the bottom bracket with translucent 3M protective film (occasionally referred to as helicopter tape).

I use 3M automotive double-sided tape to hold it on the chainstay. I've done this for a few bikes and never had a problem.

Wish you good luck.
Even the Pioneer supplied magnet is not 100% workable in full Pioneer system.

OT, do you have to use SRM's wheel magnet or will any one do?
any magnet, as long as it's pointing in the right direction (north/south doesn't matter, just that one pole is pointing at the srm)
you can get a batch of small neodymium (aka rare earth) magnets on ebay for a few £/$/€ then tape/glue one in the correct position

Ah ok. I have a Cateye magnet but the head unit isn't picking it up so I'll re-pair everything.
Thanks for the assist!

It gives off a little pip when it passes the sensor so that should indicate it's picking it up?
3m VHB tape all day. Had to use this to attach the Pioneer magnets to my frame as very few things stick to my anodized frame. VHB tape has been rock solid for few months now. Been washed a bunch too with no movement. Comes off easy enough when you want it to though
Clean frame area with alcohol. Apply a layer of tape. Place small rare Earth magnet over tape, apply desired layers of tape over the magnet.
This makes for a relatively weather proof solution. Also the chain or any other object will not be able to catch onto the magnet, and cleaning debris (all that magnetic stardust!) from the magnet is very easy. I've also used 3M's protective film (your local hardware or car accessory store) as the first layer, with success. When or if you are selling the bike you simply remove the tape and reveal the pristine frame finish.
