Wow – thanks for all the responses – went for a ride* and came back to tons more advice.
Regarding the fork, I upgraded that with the frame, went from a Tora to a Revelation. Brakes are Hope X2, gears are SRAM X9 and chainset is SLX.
The friends bike I compare it to is a Charge Duster XT. It’s mega light in comparison.
Good to hear some support for Shimano hubs – to be honest I’ve fallen in love with the Hope clacky noise but depending on total cost it’s good to know there’s a solid alternative.
*managed to stack it into a tree stump, go over the bars and rip my saddle off so there’s another purchase to mull 🙁
