i rode one of these a few weeks back, i actually really liked it, it was on a gravel demo bike from the importer, the shift was perfect, basically it felt like the best front shift you will ever get, up or down, i know that sounds dumb as it shifts in the hub but the feeling was the same. i was a bit moody with Hambini though, he gave his opinion on it without actually doing anymore than looking at the website and not actually having a hub to test or pull apart, felt that was a bit naughty of him. i do like the idea though, for me the win is closer ratio cassettes, the one massive downside of single ring systems is that sometimes there are massive jumps between each sprocket, having a hub with a drop in gear similar to that of a 50t ring to a 34t ring means being able to run a closer ratio on the rear cassette, and that really appeals to me, basically the ratios of 2 x 11 etc with the simplicity of the 1 x 11 system.
