Hi dear friends,
I'm looking forward to. Purchase this quarq powermeter, but don't know whether 8t fits a boost mtb as I've heard, that it's defined by the spider.
Thx a lot for your support

Yeah 8 bolt DZero Power meters fit mountainbikes, I have one on my Revel. I am running a SRAM provided 4.5mm spacer on the driveside btween the crank and the BB.

So it's possible to convert the spider afterwards?
Is it somewhere mentioned whether it's boost or not, I didn't see it?
Is it an old powermeter or are there any differences in quarq at all?
Thx a lot

I assumed it was Boost as it is a newer 8 bolt spider. Mine has "boost" written on it, it appears that one doesn't. It would have to be newer, again, because it's 8 bolt.

Thanks a lot, so if boost is not mentioned it's non-boost?

Did you try to put it on your frame ?
If the chainstay allow enough clearance for your ring, you can go with the non boost version.
It will be about 3mm more inboard wich can be better for the bigger sprockets and when back pedalling on the biggest one.
