I have a set as well VEL RSL 50 and yes they can run tubes or tubeless and yes the Quality is up there with the best .my mate has the dura ace C50 .and we both said they is hardly anything between them in Quality. if anything my DT swiss hubs sound a lot better And i better my Previous 100 mile time by 25mins .they are Definitely faster than 25mm rims.
