We really can't speculate tho would have been nice to have this detail therefore take it up with them and see if they will compensate you for lack of description. All you can do is pitch your case to them.


Where are you ordering your Stages PM from? Thruthfully, BB type as cheap as they are shouldn't be a driver of what PM you choose which is a much bigger deal. Shimano cranks are the best and beauty of the Stages PM is you can swap it to different bikes if you run Shimano cranks on all.
