Hands free tire mounting! This isn't the only one on the market, but it was the first I've sever seen
This tire seat is comfortable too!
The yellow and red rims are interesting, I haven't seen any 2 spoke rim before... I wonder about the balance
The above was particularly impressive, good concept for a display
If you have balanced tires, like I have, you'll probably appreciate the full range of all the weights this company http://www.cnblueocean.com/ displayed. Myself, I'm impressed.
