So, I've been riding my Rover NuVinci a while now, (just replaced the tires), and I was thinking about ways to slightly increase both the top speed and the hill climbing ability, by a small margin, without going bankrupt in the process. I saw a few earlier posts which mentioned the Patterson Transmission Crankset, and wondered if this would work on a NuVinci.
I've already flipped my Rover once, so I'm not looking to turn it into a race bike, though a few extra miles per hour would be welcome, as would a moderate improvement in climbing hills. I went to the Patterson website, and they don't really explain how their drive works, at least not to a degree that I could understand. If there are two ring gears hidden inside the crankset, would this cause chain length issues? Is the gear range, (is that the right word?), compatible with acquiring a slightly higher top end, and slightly slower low end?
I'm not an expert on bike stuff, by any definition, so I hope my question makes sense.
If I've made any blatant engineering errors with my inquiry, I welcome any wisdom which would help set me straight.
