PROS:
P9 is a very up to date enduro 29er frame. It compares to many late 2017/2018 29ers from large companies (Norco, Specialized, Giant, Transition etc) Long Reach, Slack, Long wheel base, Good Travel. (If you want XC like, go P8)
Stiffer than Aluminum (Giant Reign) in comparison.
Fast and Stable, Easy to maneuver (compared to my Medium Giant Reign)
Threaded BB
Decent Progression on shock i believe like 28-30%, so Coil is compatible.
32 pounds weight.
CONS:
Not extensively tested so don't know about durability, but you pay for what you get.
Bolts and Nuts are not greased at all. Built in nuts (Shock, Brake Mount) seems like they use a soft aluminum so it may strip easily if threaded wrong or forced.
Bearings generic, don't know how well they will hold up.
Too many internal cabling holes (water will get into the frame).
Lacks Protection (BB, Downtube, Chainstay/Seat stay). Had to install my own.
32 pounds weight.
This is what I can come up with so far. Ask more questions and I can help out.
