The Abec 11 83h 78a wheels rock!! The bearings are right in the center, so you can put them on any way, and rotate them for more even wear. They are super fast, and don't get caught on rocks, or even train tracks! (especially if you have the 101mm ones) What a coincidence! The person that took the picture of these wheels has the exact same name as me!

These Abec 11 83h 78a Flywheels are very fast and grippy yet very predictable. I noticed an immediate difference in handling and stability and they are also very smooth. The bigger flywheels are better but hard to fit on most boards - these are the next best alternative.
