Wow, since changing over to NNN, I'm really behind the times. There is
a Propulse classic and in two versions. It seems Salomon finally
decided that wider under foot gives more stability and perhaps push
off. Mark Wachter describes compatibility in part in his review of
the Propulse:

Isn't the Propulse for skate? Which boots do you have? If the

is the flexor. Classical = 85(?) or may want to go one stiffer. I
may still have some around.

I need bindings for new roller skis and am totally confused at what
Salomon now offers for classic. The least expensive option is
actually a "Sport" pilot binding that looks a lot like the skate
binding (rigid piece that connects to second bar).

People have described a kevlar strap as part of the race classic
pilot binding, but this version looks like it doesn't have that (so
might actually be an improvement for roller-skiing). I have one
pair pilot, one pair old-style profil classic boots--ideally I'd
like to be able to use either, depending on how much ankle support
I find I need.

Then there's the Propulse, which people say can only be used with
newer pilot soled boots--though it's not clear why. Then there's
old-style pilot (which, unfortunately, is actually out of stock
from my discount source).

Any advice appreciated.

The setback is different for the newer Pilot boots, and Propulse
bindings use a different flexor. You can get a Propulse flexor for
older boots. Unfortunate that they had to go that route though.
