I don't know what will work on my current bike. I think the Oval cranks I have use the GXP platform but I'm not sure what that means as far as compatibility goes. I currently have a Planet X Pro Stealth with an Oval Concepts 520 crankset and am wondering what type of crank based PM I can install? I assume I could also get a stages PM but I think I would need to replace the whole crank as well (correct me if I'm wrong). I'm not very mechanically inclined, obviously, and I'm not sure what type of BB I have and don't want to get something that won't fit on the bike.

Also, if anyone has a used PM in good condition at a good price that would work, let me know what you've got and the cost.
