What BB is your bike? I was going to get another Power2Max for my Exploro but learned you can’t use P2M with SRAM cranks on a BB386 frame. I’d work fine with a Rotor crank but I already had a SRAM Red 8 bolt crank and didn’t want the added expense of switching cranks on top of buying a power meter so I bought a Quarq Dzero. I’ve got about 1k miles on it and so far It works great
