They’re fine but nothing particularly special. So using them as a model, I would guess that there’s plenty of rims with internal width of 22-24mm that weigh about the same, approximately 400g.


Definitely sub 385g carbon rims exist. I think I’ve seen 250, so that is substantially lighter. Shopping around though, many seem to weigh what aluminum ones weigh, between 380 and 420g. With extremely similar internal width, though the external width is quite a bit more.

Most of the ones I’ve seen aren’t what I’d consider aero, sorta deep (40mm or so) with a slightly rounded surface.

For adventure type of riding, 10-15mph, on everything from pavement to “blue” MTB trails, I just don’t see the advantage.

Im not against carbon for racing, especially road. I also recognize some inherent advantages for a burly MTB wheel.

I think a lot of people equate carbon to lightweight without actually checking the weight.
