Interesting. I can see some future use of that in the type of races we currently do, in terms of having the ability to steer your bike to pick a particular wheel to be on witin a group - that might be fun if they get it to work well. My main concern with that though would be my potential to drop sweat all over my phone if it's mounted on the stem like that - I tried that before soem time ago and stopped mounting my phone there for exactly that reason!An interesting read about Zwfit's demonstration of steering and mountain biking at eurobike:
