Familiarity: I've put it through the wringer
On my scale they came out at about the listed weight. Routing is tricky, but doable for brake lines only: fitting a brake line and cable housing through those openings seems unlikely (at best).
Otherwise, they work like handlebars. The flattened tops are comfortable.
