Large alloy frame, DT skewer, seatclamp, and shock (I.E. as it comes out the box) I measured at 4.4kg, so pretty porky. However, I built mine up (with XTR, DT wheels, Hope etc) and ended up at pretty much the same weight as an off-the-peg ‘C’ build for about the same price. Except I have XTR, not NX…
The C and CC frames are signifcantly lighter, based on holding them in store – I dont have figures though and have never seen any.
The long thrad on MTBR is probably your best bet, 141 pages and counting… https://www.mtbr.com/threads/hightower-v2.1107287/
(Remember you cannot buy the C frame only the CC, although theres not much in it between those two variants)
