Why buy that why you can get PX's offering with force for the same price?
It's all Apex on that Planet X except the shifters and mechs. Which is odd because the Apex mechs would probably be better for audax riding. The long cage Apex rear mech gives you the gear range of a triple (Force doesn't) when running it with the Apex chainset.
I'm not sure the Planet X can run 28s with guards either.
No rack mounts, and less clearance on the PX.
Then add what miro said here.
