Weight: WTB KOM i23, Alex TD26, ZZYZX X-Force Rims

I was building new front wheel for my Norco Sight, and decided to put on a scale some rims I have.

My new lightweight 650b (27.5") rim WTB KOM i23 and it's weight is 420grams

Stock rim from my Norco Sight Alexrims TD26 (650b 27.5") and it's weight is about 460-470grams.

ZZYZX rim from Corratec X-force 0.3 2012 is rather lightweight and very very strong. It is 26" rim with 470grams of weight.
