I'm running a set on my TR250 and love them. They feel very stiff/strong. (They dont have 37 holes drilled through the rim. Just one for the air valve) I like to run tubless so this is a huge plus for me. The only thing I don't like is I think the center of mass on these wheels is brought outward by the ridge in the center of the rim and the round part that joins the spokes on the end. Other than that they feel like regular mountain bike rims.
