Proski vario rollerski

Hi

I'm considering buying a new pair of classic rollerskis- my old Swenor
are broke.

Noticed that the Proski Vario model got a system with a speed reducer
for increasing the resistance.( http://www.pro-ski.com/start.html)

Has anyone experience with this system, particularly the durability of
this system?. Or should I rather opt for the ski without speedreducer
model C2?

I've been trying to find an european online store selling Proski
rollerski without luck- If anyone knows a online-shop that is willing
to ship to Copenhagen, Denmark - please let me know.ke to hear

Thanks

Jonathan

There is a page with 20 other brands pf rollerskis

in case you have no luck with finding retailer in Europe.

Speed reducer of this type is used on many other models and
is available separately.
