After a little reading, the DUB bottom bracket uses a 28.99 spindle size. So in order to use it you as OddSlugg said, you’ll have to also get a new bottom bracket that corresponds and fits in your frame for that crankset.

There are lots of ways to can go for a power meter with the easiest being Shimano, since based on your pictures Im guessing you have a shimano 24mm BB, cranksets with stages power meters. They have both dual sided or just left sided power meters.

Or if you want a Quarq as you posted above, you would have to look for one with a GXP crank like this.

Could also look at power2max such as these.

Or this this way and get just the spider and then a sram force 22 gxp crankset that would fit your BB.
