Pumped Up

I recently bought this Giyo double action air pump from our local bikeshop - Bisikleta, I had to buy one because my centennial pump got busted. And while window shopping this hub series caught my attention and reminded me of my busted identical hub

While this hub caught my attention as a replacement for my hub with broken wings, but then again my decision of buying this part is put on hold because of the fact that I am not sure if Shimano revised the pawls of these hubs.
