We spent some quality time at the Lahr booth, neat concept,we'll shoot more pics but they'll be everywhere soon. Gear ratios are 1:1 to 1:3. In short, rocker cams roll over a delrin hub that is roughly a cone shape. As the rockers move across the cone gear ratio is changed....
that made no sense at all but the pics will help.

Saw the sunline stuff, should we say "Dminor from the internet" gives a shoutout?

Haven't been too impressed with Gboxx stuff as of yet. Either companies are holding their cards or the engineering has reached a stalemate.
