Hmm
Personally:
Thomson seatpost on a hardtail? Aren’t they meant to be quite stiff? For Thomson money I’d probably have gone on-offer carbon post and pace carbon grease/paste, (or maaaaaybe a USE shockpost)
XT crankarms, but you’ve ditched all the chainrings? As far as I can work out, almost all the 36?g weight difference between SLX and XT is in the chainrings (alu, carbon/steel, alu vs. steel, composite/steel, basic alu
“another silly billy with wrong frame size and too much seatpost up their back hole”
Eh? Its a 130?mm (more?) forked hardtail with 70?mm stem, HR up front, I don’t get the impression its built up to be a long TT efficient pedaller?
