I didn’t find such a light rim as replacement of my 36er steel rim in the past and so I decided to build my own rim. I rode it for nearly 3 years now. It costs about 36€, weights about 619 grams and it has 36 holes. The rotating mass of the total wheel was devided by two. Astonishingly I didn’t notice so much difference while riding. But it is much easier to carry.
The main problem was that my rim requires a disc break and it took 1 year to design a disk break mount for my square taper generation 1 Schlumpf hub. As shown somewhere here in the forum, my rim has the theoretical advantage that it can be dismounted into 2 parts for traveling.
