The 98SL uses the same wheels and tires as the XL98R skate ski. The wheels are mounted on an existing aluminum frame which is much less expensive to produce than the composite frame.

The 98SL accepts the same optional Speed Reducers as the XL98R, but due to the older frame construction the brake for this ski is the V2-B100 instead of the XL brake. This is an excellent skate ski at a very attractive price.

 
Internal Speed ReducerISR & ROLLING RESISTANCE: The rolling resistance of tires is dependent on the amount of energy absorption. A fast tire absorbs very little energy while a slow tire absorbs a lot of energy. Slow tires can become extremely hot, so hot that they rupture. Instead of using high energy absorbing rubber, V2 uses a patented kinematic damping system to increase rolling resistance. But, with a split rim we cannot employ our standard kinematic system. In order to increase rolling resistance we added a 22 mm pocket on the inside of the split rim. In this pocket we press fit the ISR ( Internal Speed Reducer). The ISR has two elastic sealing lips that rotate around a very precise hardened steel spindle. Between the two sealing wipers is a high viscosity lubricating fluid. This system increases the rolling resistance by about 15 to 20%. The heat generated is dissipated via the aluminum bearing tube and aluminum bolt fastened to the wheel forks. So, with just one tire you can have a ski with three different speeds. Put an ISR into one wheel of the ski and you have a slower ski. Place the ISR into both wheels and you have the slowest combination.
 
SPLIT RIM & TIRE: Shown above is the split rim wheel assembly. The two split rims are compressed by four small socket screws which engage threaded inserts in the rim. The tire is made of solid rubber and is captured by the split rim. Since you only replace the tire it is much less expensive than replacing tires molded to a plastic or aluminum hub. The tires are available in two profiles.
 
V2 XL100R Speed ReducerSPEED REDUCERS: The patented Speed Reducers have been praised by skiers from around the world. In some locations it would be impossible to roller ski safely without using Speed Reducers. The new XL98 Speed Reducer has a neutral position and four resistance positions. Former Olympic Biathlete, Dr. Robert “Duncan” Douglas is a ski tester for V2 Jenex. He called to let us know how the new XL98 tires were performing.

“Have skied about 150 kilometers on the new tires. Found a long steep downhill, almost 3 miles long. With the Speed Reducers engaged and tapping my brake I made it down in control.”

 BRAKE: The patent pending brake has been an outstanding success. The new XL version mounts directly to the rear wheel fork and is 30% lighter than the original brake. When not in use
the brake is folded over the ski binding.
 
"This finally puts every roller skier in control of his or her destiny. Before this, you couldn’t actually stop yourself on down hill, at stop signs and in dangerous situations. The brake is mounted on one ski, is very light weight, not too costly and is easy to attach. I can attest to that. There is a learning curve, of course, so be sure to proceed cautiously in your beginning kilometers of use. Just as 100% of roller skiers should be wearing helmets, the same number should be using the brake.” Marty Hall, former US Olympic Coach and both Coach & Nordic Director for Team Canada.
 
 
Wheel aligmentWHEEL ALIGNMENT: Most of us are not anatomically balanced, so even though the wheels and bindings are perfectly aligned the ski might pull in one direction. This alignment lever makes it very easy to align the wheel. Simply draw a pencil line along the side of the lever, loosen the nut slightly and then move the lever forward if the ski pulls to the right and backward if it pulls to the left. It’s simple and it works.
