: Yeah, those are great, if they really work as advertised. But they are pricey.davidb
: Rollerskishop actually seems to suggest that it is the rubber compound that make the difference. Here is what they say:
Choose your speed from 3 different long lasting rubber formulas that we guarantee for one year from defects.
Anyway, FWIW, I ended up buying a pair of V2 XLQ98. I can't really compare them to anything, since I have never skied anything else, but "so far so good", after maybe 100 km or so. The speed reducer is actually pretty decent, I think. It is easy enough to reach while in motion, so while not a real break, it can help you bring speed under control on a downhill, which is a very big plus, IMO.One interesting thing about the speed reducers
that I never saw mentioned: On a downhill, if you lift one foot, you immediately accelerate, quite unlike real skis! The reason is that the speed reduction has nothing to do with the weight you put on the wheels - it is just a fixed resistance. You lift a foot, you get half the resistance
Snow skis are not at all like that, for obvious reasons. I am assuming that using slow rubber compound, instead of speed reducers, will more closely match the real-ski experience.
