Heat limit for v2 rollerski wheels?
I have a pair of v2 roller skis, I don't remember the exact model but 900
seems to have been in the series number. In the past, wheels would have lasted me a year or more but lately, I have gone through 2 sets of back wheels in the last three months. They both melted down. Today, I could possibly understand. It was 80 and I was on good blacktop, so there was some heat on the road. Today it happened while double poling downwind on the flats. The first set melted down in May and temperature shouldn't have been a factor. Anybody else have a heat problem with their v2's. Mine are the wide wheels, on skating skis? |

I think you need to be more clear about "melting". Are you talking about
excessive tire wear. Never seen a wheel actually melt down like a candle. I've owned all the different Jenex V2 wheels e.g. 900's, 800's, Black Mamba's, and Aero 150 and 125. The 900 series wheels always wore out significantly faster than Pro Ski wide rubbber wheels and Elpex rubber wheels. If I'm not mistaken the Jenex 900 wheels are a sythetic rubber, which doesn't absorb vibration as well as the 100% rubber tires. It's odd because one would think the harder charactereistics of the Jenex 900 would make it last longer than a softer wheel, but I found the opposite to be true. The Jenex 800 series wheels used on skaing models wears super fast compared to other skating wheels. My friend replaces his Jenex 800 wheels every other month. Marwe and Pro Ski both have hard narrow wheels which significantly outperform Jenex 900 and 800 wheels for skating. In fairness to Jenex their Aero 150 wheels last longer and offer more comfort than any wheel on the market. To bad this wheel isn't suitable for classic. The Aero 150 is so tall and narrow it is next to impossiblle to classic roller ski without outriggers. Than again the outriggers add weight and are akward.

When you say "melt", do you mean that the wheel suddenly wears down in one ski session? Or is the wheel slipping on the wheel axle (which I've never experienced)? Yes, melt as in the material near the bearing gets hot and squishes out. It happens in one session. The tires are not really worn, but end up with a flat spot that eventually will make the tire fall apart. These are the softer black "rubber" tires. I seem to remember a lighter colored back tire, whatever those are made of or could those have been on the proski's I use to have? Yes, the ProSki tires lasted a lot longer but I like the brakes on the v2s. Bizzare. I've heard of that on other rollerskis, but not the Jenex 800 or 900 series. I'd give Len a call at Jenex. Manufacturing defect? |

I use my Aero 150's for classic in the lawn at a local park. They are
much more stable here than on pavement. It also has better simulation to snow when driving the leg forward thru the glide phase. Tire wear is non existant. These are great golf course skis. The poling is much better in the lawn too. Try it. Dave "Douglas Diehl" wrote in message ... I think you need to be more clear about "melting". Are you talking about excessive tire wear.

If the wheel material at the bearing is getting soft and squishy then the bearing must be getting very hot. Do these bearings need to be lubricated? I assume they are "sealed" bearings (little rubber disks are there to keep dirt out). Is it possible that crud got into them (e.g. have you been rs-ing in the rain or at the beach?) I've never used these rollerskis but I hate to see people troublshooting a problem and missing the obvious sign of where the problem is... Bob |

With these skis, you buy the wheels and bearings as a complete unit and they are sealed. I'll will take the advice of trying to get some credit for them. This is the second pair in three months though and this pair only made a few trips on clean flat blacktop. I've been using the same wheels for probably 3-4 years without much trouble. Ah well, thats what we get for not being in a mass market sport ;-). |

It is "normal" for the viscous liquid to be expelled from the bearings on
Jenex 900 and 800 series roller skis. I believe that through time the loss of this stuff makes them faster. I do recall hearing about a problem with tire melt on the 900 or 8000 series, though I never had trouble with that, and I thin it was confined to certain manufacturing runs. The profile of 900 wheels have changed through time, and I seem to remember it was the earlier wider tires that had this ,melt problem.
