Already has Ti pedal axles, BB and singlewalled rims.
Personally I'd stick with the TryAll tyres, a little more weight for considerably more grip and puncture resistance.
Neon 2012 rims front and rear- very light.
Zhi CNC cranks- new ones are a reasonable amount lighter than the tryalls.
Ti rear sprocket.
Ti/ Alloy bolts.
Ti hose fittings.
I don't think sub 8Kgs is possible with this frame (it is 1.7 Kgs), unless you want to get skinny puncture prone tyres and uber expensive carbon forks.
I don't have a Ti BB or carbon forks, I do have Tryall Stiky lite/ Shift tyres and what can be changed to Ti/Alu has been and it's around the 8.5 Kgs mark.
