QUESTIONS ABOUT ROLLERSKIS AND POLES
Generally, the biggest influence on rollerski speed is the wheel
compound. Racing rollerski wheels are made out of hard urethane (?) and the softer wheels generally are slower. The bearings have a significant influence, but it's mostly the wheel compound. -Nathan http://nsavage.com "Mike" wrote in message m... My speedskates have "normal" 80mm wheel. I find my rollerskis to be much slower than my inlines. You should also know that rollerskis are much more unstable than inlines. If you want a fast ski: The V2 Aero 150 can be pumped up to 100 lbs psi and move pretty fast. Pro-Ski S2 skate rollerski are fast - I set a PR around Kensington Metropark on a pair, without really trying. Avoid the Aero 125 - you've probably read the horror stories about wheel failures in this forum. Not sure that wheel diameter makes a difference in rollerski speed. I've been evaluting a pair of Pro-Ski S3 rollerskis with 23mm x 100mm wheels, and they're slower than my Aero's pumped up to minimum pressure. I think wheel hardness (primary) and bearings (secondary) make the difference in speed (although I'm no expert in materials technology - just my guess). Mike |

QUESTIONS ABOUT ROLLERSKIS AND POLES
The r.skis that can be most easily slowed down on demand (both for
negotiating hills and for better resistance) w/o frying the wheels are v2 aeros 150s. You have to lean over though to engage the speed reducers, which personally I don't have a problem with. 150s are also good for bad pavement and for the occasions when you have leaves/debris on the pavement e.g. after a recent rainstorm. Note that inline skates in general are much better in rolling over cracks/rocks because the 4 wheels in inlines essentially have no gaps between them. |

QUESTIONS ABOUT ROLLERSKIS AND POLES
When I follow European rollerski competition (rollerskitour.com) I
don't ever see aero wheels. If what Mike saying is true and aero wheels are faster than solid PU wheels why aren't nobody is using them? My expirience as a speedskater tells me that harder wheels are faster as long as rebound is there. I've never tried "pump up" wheels, of course, but they should be softer than soft skating wheels for sure. What I see on photos from races they use short (530mm) rollerski with 100mm wheel and that's it. No 125 Aero, no 150 Aero or any aero. Can somebody clear that matter? This is important because skating industry is moving towards 100mm wheel not being on 84mm for a year. Nobody half-way serious is talking about 80mm wheel any more. If all this is going to settle on 100mm, we will have a host of wery good quality, wery fast wheels for various conditions for skating and rollerskiing alike. Remember, pro speedskaters do marathon in 1 hour (which is 26 MPH last time I checked). |

QUESTIONS ABOUT ROLLERSKIS AND POLES
"revyakin" wrote in message om... if your objective is to TRAIN on rollerskis to prepare for snow skiing, the slower the better (safer too). I disagree slightly. There are many rollerski wheels out there that are too slow - they slow down the motion and do not imitate skiing very well because of this. It depends on what you're trying to accomplish as well. If you want aerobic training, slow rollerskis are OK, but if you are trying to work on technique or speed, a little bit faster than snow seems to be the best, especially for people at altitude. -Nathan http://nsavage.com |

QUESTIONS ABOUT ROLLERSKIS AND POLES
Thanks, everybody.
I need rollerskis for training and being in Bay Area I would use them a lot as preparation for snow (6hr. away from here even in winter!). And I can rollerski practicly of my porch (next to Pebble Beach - no traffic, good road w/rolling hills along the Pacific) But at the same time I want to organize some kinde of racing and at least not to loose skiing frends during summer. Local outdoor speedskating races can let rollerskiers to participate. They are looking for more people and nothing is wrong to have rollerski category. In fact this is way better than wait for Rollerski Federation to acknowlege California existence. They are too busy with Turkey (you know, another Scandinavian country) and stuff. So, my idea is to use racing rollerskis (and the same wheels I use for skates) for training and just slow them down with reducers, short bushings or rubber rings or use "dead" skating wheels, 100mm scooter wheels ets. or even 80mm wheels. Melted wheel hubs is new phenomena to me - probably "shot" bearings more than load (there are 2-wheels skates and they work OK). Some new skating wheels have carbon or Alu. hub, so no sweat, they will not melt. If anybody is interested in new generation 100mm skating wheels presumably applicable for rollerskis I should know thing or two. |

They are looking for more people and nothing is wrong to have rollerski category. Cool. I may go to Bay Area within an area for a job interview, so I could probably join your race. 6hours from snow? Isn't Royal Gorge relatively close? I remeber making it in 2.5 hours. Don't expect, as a rollerskier, to go faster than speedskaters, even though you will have poles. On speedskates, you turnover is faster than on rollerskis, and the technique is slightly different. I am going to California in October... but I'll be in LA area. I am planning to drive North to Fresno area and to try to rollerski up to Giant Forest from Three Rivers... 16 miles or so. Will have to convince my girfriend to wait for me with a car on the top. |

Cool. I may go to Bay Area within an area for a job interview, so I
could probably join your race. 6hours from snow? Isn't Royal Gorge relatively close? I remeber making it in 2.5 hours. You were probably driving from the City (SF) and it is about 2.5 hours from SF to the Gorge. Serge lives in Monterey, which is over an hour south of SAN JOSE, which is about an hour south of SF. So,...do the math and you'll get close to 6 hours. Montecito, Yosemite, or Bear Valley may be closer for him, I don't know. The best place for a rollerski race is probably on Canada road on a Sunday, where you (Serge) were a couple of weeks ago with your speed skating buddies. I was one of the guys out there on rollerskis. My buddy and I used to do time trials there in the fall, but he has a kid now and I, well, I have no excuse. Not to pour cold water on your idea of rollerski races, but I would forget it in the bay area - most of the skiers who live there have to be pried off their bicycles every November. If you want to race, check with Far West Nordic in Truckee and see if there is anything going on up there, either formally or informally. But then you're stuck with that 6 hour drive... bt |

QUESTIONS ABOUT ROLLERSKIS AND POLES
I'm glad to see someone question the use of higher forces in rollerski
training. Nathan Schultz wrote: . . . if you are trying to work on technique or speed, a little bit faster than snow seems to be the best, especially for people at altitude. In previous years and in other sports I've always put a lot of emphasis on training with higher Force. And since slower is usually safer for rollerskiing, that fit for me choosing slow rollerskis. But in fact true physical Power (the main driver of racing and hill-climbing success) has two other equally important factors besides Force: Muscle-Push-range-Distance and Turnover-Frequency It's interesting to think of training as the application of Race-pace or above-Race-pace stress on different combinations of those factors. My tendency has been to focus on just Force, or maybe the combination of Force and Muscle-Push-range-Distance (like plyometrics or strength training). The big neglected factor in my power-training has been Turnover-Frequency. And especially the _combination_ of Turnover-Frequency with Muscle-push-range-Distance. Seems to me the use of slow rollerskis makes it nearly impossible to apply an above-Race-pace training stress to that combination of critical Power-factors. But I still like to use slower rollerskis a lot, because my biggest dryland training block is fear. And because it partly simulates hill-climbing, without driving to an actual steep hill (and then figuring out how to get back down it again). Ken |
