• Not imaginary. I have two, grey anodised. I weighed them both and they came out at 450g +-2g. I know this because when I built my burls, I weighed everything to satisfy my spreadsheet OCD.

    For reference, these were bought in October 2012 from BLB.

  • Fair enough, but the ERD hasn't changed... if yours are lighter and you say thinner inside, then they should have a lower ERD than the current ones (not higher). On all rims I have always measured 592
