Dan, in fact the Andra 40 weighs almost 100 grams less, per wheel, than the Andra 30. Strange eh, considering the 40 has Ryde's highest load rating?

Pavel,
Looking at the pages you linked to The 26" version of the Andra 40 is 825g and the 26" Andra 30 is 696g.
Edit: Oh, Scratch that, I see Dan has first-hand knowledge and Ryde's figures are erroneous. I should know better than to start answering a post before finishing reading the thread. lol.
