The units I received were intended for a carbon fiber tubing that was exactly 16mm inner diameter. The bearings are a smidge over that, like 16.06/7 in diameter so they do not fit. i will have to sand them down a bit in order to work for their intended purpose. That being said they are very rigid and seem durable.
