Much Like the original Super Pro Wheels the new Haro Vintage wheel set includes a sealed bearing hubs with 3/8" axles in both the front and the rear. Of course the rear is set up to use a 16t or larger freewheel just like the original wheels. They are then laced to a Super Pro shaped rim with a high polished finish. Of course the wheels are finished off with Haro Lineage Peregrine like graphics on both the rims and the hub. Other than actual Peregrine Super Pro wheels these are the best wheels you can get for 80's and 90's freestyle bike restorations.
