Correct.
Kinlin rims can be found under a wide variety of brand names and are found on many different brands of pre-built road wheels. However, as far as I know, the rims alone are only available unbranded or branded as IRD rims. There are also 27 mm and 38 mm versions available. The main appeal of these rims is that they are the lightest aluminum clinchers available (per mm of depth). Despite their light weight they have a nearly flawless reputation for being strong, dependable rims and they are reasonably priced.
I've been using the 30 mm version for years, with reduced spoke counts, with no problems on both road wheels and fg/track wheels.
