Made some changes, thought I'd post them up.
Modified rim, Revolution spokes, 17:15 gear ratio, Trialtech SL single speed spacer and a new Rubber Queen tyre:
New brake pad refills, best I've ever run. Beat Coustsinks hand down:
And Trialtech High Riser bars + some headset spacers to bring the bars up and backwards:
Currently 8.38kg. Going to leave it at that, maybe try a Pure '11 frame in a few weeks.
