Yeah. But I still think Open Pros could a decent choice. Not too heavy, but they'd last.
Part of the way Klinin save weight is by having a thinner braking surface. So the Open pro will be slightly heavier, but that weight is basically in two places. More braking surface, so longer lasting, and spoke eyelets, which allow for a easier build, and a more resilient wheel.
So Open pros may be slightly heavier than some weight weenie rims, but there's not an once of fat on them.
