Power meter for MTB

[Santa Boy]

I have had a look at all the options and I am leaning towards a Quarq. Question is this:

Will this work on a 3x10?

Who in JHB stock this?

Any other options I should consider?

No. Only two chainrings

It comes in via SRAM. If it's available, anyone who has SRAM should be able to get one.

SRM, Powertap.
