Kinlin are a Taiwanese manufacturer of bicycle rims and they are very good at it too. There rims often get rebranded but here they are with no decals.
The XR22T is a 450g rim that is 24mm wide (19mm internal width) 31mm deep and is therefore an aerodynamic alloy clincher rim that is also tubeless tyre compatible. It's width and depth make it very stiff allowing lower spoke counts. Better still there is an offset drilling option so rear wheels get a better tension balance. Tension limit 1200N.
The symmetric rim brake rim is for front wheels and the asymmetric rim brake rim is for rear wheels. Spoke length for the asymmetric rim are unchanged.
Kinlin use a KLM41 aluminium alloy (niobium is one of the alloying elements) to create a round and flat rim. It has a thick spoke nipple bed so is fine for any rider. spoke nipple washers help though (I build them up with Sapim HM washers).
The rims is more than suitable for road riding or racing or CX use and those that just want to ride can all use this rim. I am actually struggling to find anything I don't like about.
The rim is tubeless tyre compatible. See the wheels I build with them - BORG22.
More stock than I list is available.
