Hi, everyone. I'm looking to replace the stock rear shock on my 2021 Trek Fuel EX 9.8. It is an X-Small frame. I want to know if I will have enough clearance between the down tube and air can with a DPX2? The reason I am asking is I have noticed what looks like a cutout to allow for a piggyback on a friends Fuel EX. Mine does not have this so I do not know if it is incompatible.
