Series Alpha
α TPU+TPU, thermoplastic polyurethane injected onto a thermoplastic polyurethane center
Elastic Polyurethane wheels Series Alpha

F.I.R.’s top range, the Alpha series, features a combination of hub and tread both made from top quality TPU. These wheels have both mechanical and chemical interlocking systems making them exceptionally strong. They are ideal for high speed applications of up to 10 km/h or 6 mph. They are very durable and resistant to tearing. The elastic polyurethane, from 70 to 80 Shore A, allows excellent grip and the ability to overcome obstacles. The wheels are noiseless and do not vibrate; they are suited to most surfaces.
