"It's the best tool on the market for seating tubeless tire beads because it's so easy to use," says Norm Demers about his company's new lightweight, portable bead seating tool.

The Astra "Bead Seater" consists of an air tank that simply blasts a volume of air into a tire to instantly snap the beads into place. To use, you slip the wide, flat spout between the bead and rim and push a but-ton to release the air. Blocks should be used to keep the wheel rim off the ground.
