Albion X-treme wheels are a popular choice for solid polyurethane. These wheels are manufactured using a proprietary poured-mold technique, which results in a cleaner, smoother looking wheel. XI wheels are designed specifically for high-capacity manual applications involving chemical, solvent, or water exposure. The crowned tread and x-tremely low rolling resistance make this wheel a number-one choice for ergonomic performance.

The one-piece, solid construction affords freedom from tread separation, with an exceptionally long life. An X-treme solid polyurethane wheel is non-marking, and provides excellent floor protection. XI wheels have a harder tread and slightly lower load capacity than their XP counterparts.
