power meter for MTB

[jcr]

Wondering if someone has a recommendation for power meter for MTB or should I say for 73mm width BB shell. I don't think I see too many options out there.

I do have a XCadey spider that is 3 bolt with Zrace RX crank set but seems like the crank spindle is not long enough. If someone has a recommendation for crank then I can reuse the spider. It seems like the spider has quite a bit of offset.

I'm using a Xcadey Xpower-s gen two on Shimano SLX cranks and I'm not sure if I can recommend it. The first unit died within a couple of weeks. The replacement seems ok after a couple of months (but it's been dry)and the readings are consistent, if about 10% higher than my Magene pedals or Kickr smart trainer.

Yes I have heard some mix quality on gen 2...I have gen 1 but I guess for road.

I don't think Magene has SPD (MTB) power pedals?

I've got some Magene P715's on my road bike so swapped them to the mtb to see how close the results were.

Solved my issue today running the Xcadey Gen 1 spider (3 bolt 110BCD for road). Works with 73mm BB shell if you run it with a MTB crank (longer spindle) that is also 3 bolt. Bike is BSA bottom bracket, so I had to run 2.5mm spacer on the drive side. Added an addition 0.5 shim onto the bottom bracket to give it a little better chain line.
