Bike-ball tubulars, from 20 to 26 inches: grippy tread, fabric-protected sidewalls, reinforced rolling area.
The B3 is the tubular for bike ball (cycle-ball). The discipline is brutal on equipment: the bike is thrown sideways, the wheel is used to strike the ball, and contact with the opponent and the boards is constant. A road tubular wouldn't last a half.
The The tread is grippy and thickened in the contact zone — the one that strikes. The sidewalls are lined with a textile layer that takes lateral friction and impacts. Standard puncture protection completes the whole.

An extra layer of rubberised casing under the tread: a sufficient barrier against most punctures, without hurting efficiency. |
Compound for parquet and plastic floors (cycle-ball, artistic cycling, wheelchair): grip, liveliness, and no marks left on the floor. |
