Very nice bike!

Seatpost - as mentioned
Carbon fork with long shaft (since you never fold) like on the pic attached
Short carbon handlebar (540mm?)
Litepro Ultimate brake levers
If you dont want to keep your grips - get a pair of light foamies like propalm

Did a few of your customizations to my Java Air too, the seat clamp was'nt working for me, i'm too heavy
