Ordered my first two MICRO AIR-FILLED 200mm Wheels, tried them out on my A5 scooter, they were so nice I ordered 2 more wheels (for the spouse's scooter, she liked the ride on mine too!). Shipping was free and very fast (yeah Canada). Installed these wheels on a kick scooters that originally had hard plastic 200mm wheels installed, the ride was hash with the original wheels. Installed the new MICRO AIR-FILLED 200mm Wheels with a few washers added to take up the extra space on the A5 scooter axels., Very nice fit! Amazing, the ride is now very smooth, cornering is very grippy. Anyone thinking about an upgrade to their 200mm wheeled scooter should try these wheels, there is no going back to hard plastic wheels! Now if only MICRO had a suspension upgrade ... hmmmm.
