Comments about JENEX V2 Aero 125 Skate Roller Ski:
25 yrs of roller skiing on everything out there. Keep your tire pressure up & if you weigh more than 150 lbs., the brake & speed reducer will produce lots of heat on long descents. Heat is hard on tires. Buy a solid rubber wheel model if you will be on long steep down hills a lot & weigh more than 150 lbs. But you'll miss the most fun roller ski out there.
