I do not think I have any more speed for driving these. Compared with the previously used Sunringle mulefut80sl rims, weight decreased by about 800 grams.
Almost a kilogram, it's quite a lot. Any kind of path has become run off, and I used two ring sizes in these, Schwalbe jumbo jim snakeskin 4.4 "and most recently, Schwalbe jumbo jim addix 4.0".
The smaller is better, I think. It's a little lighter and it's not so big in the air space.
