ok just to add into the mix, it took 2 days from placing the order to arrive at my door, this was the 29’er imbred swap out frame.
but here is the but, i too was baffled while ordering parts away that i called on one tech customer support and got eh feedback with the one in front of him that yes the down tube is not reduced like on other frames and is actually a 29.8mm so i would need to buy the right mech for the right size..
after a little heated comments i ended up no clearer on what part i need now so still searching, i think i will take down to LBS and ask physical sight of it and get the answer that way (i don’t own verniers)
but waiting for all parts to arrive before getting it out of the box to build (minus front mech)
lets hope someone who actually has one and know’s what front mech is fitted will clear this matter up
