Shimano Stepless Rear HubGear?

Hi, has anyone heard of a Shimano Internal Gear Hub with a stepless transmission similar to the DeVinci?

Bikes: I never learned to ride a bike. It is my deepest shame.

I believe the company you are thinking of is "NUvinci"..

And, no, I havn't heard of any CVT hubs from shimano, but I would be surprised if they didn't have a design somewhere in the works that may or may not some day reach production.

Bikes: '96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '20 Surly Midnight Special, All are 3x10. It is hilly around here!

Speaking of NuVinci, after a fair amount of initial publicity they seem to have fallen off the map, particularly in bicycle applications. The hubs were interesting but extremely heavy and expensive. Are they actually being used in any application anyone knows of?

Thank you, yes, I meant NuVinci, I was talking to someone the other day and he said there was a bike coming out with a Shimano version. Must go back and find out if he ( or me ) has his facts straight.

They are still around. They have released a "Mk II" (not sure what they actually call it) CVT that is a little lighter, and seals better. The motorized bike guys really like them, as they seem pretty bombproof, and the weight is not so much an issue when you are not limited by human physiology. The gearing range is wider than any IGH except the Rohlhof speed hub, and the price is ~ 1/4 (street) to 1/3 (list) compared to that.

I'm pretty sure you can still buy a couple of OEM bikes that spec them.
