It's a good quality double-walled rim. I've had a 700c version on my commuter bike for the last several years and it stood up pretty nicely. In fact, it's still in business. Recently I bought a 27 inch set to build up for an old Fuji S10-S. Also note that you can pick up the 27 inch rim for $29 at Alfred E Bike in either 32 or 36 holes.
