Over 1800g according to this link (Unless there’s another set?)

I have just swapped out my croix de fer frameset for a tripster atr frameset – the tripster very smooth over bumps, but the cdf was less slack and so more lively and still pretty good over bumpy stuff and I sort of miss it. And I only saved 2.4lbs in weight as my build was 22.5lbs and the tripster is 20.1lbs.
