Spitfire Formula Four 99D Tablet Skateboard Wheels: Set of 4 for Superior Performance Review

These are the first Formula 4 bikes I've ever ridden. I can't believe they have a 99 durometer because they go over cracks so smooth and fast and the tarmac doesn't slow them down at all. These are the perfect wheels for the street, they are fast and offer great control. Formula 4 is definitely the best wheels.

I've been using the Spitfire for 20 years now. They only get better over time. My first pair were great heads and it's nice to see they're still around but I decided to grab a pair and try them out as I haven't ridden for a couple of years due to injury but they are fantastic they grab, they slide they make everything perfect and i love the way they are carved.

While not ideal for overly rough terrain, they ride great on slick concrete, they don't scratch as easily as other hard wheels. after only a month of use i have had them for a while and they are only a little discolored where the wheel touches the ground. I really like them and would recommend them to anyone looking for good hard drives.
