Albion TR wheels are heat-resistant phenolic resin wheels. Similar to the Albion TM wheels, these wheels are manufactured from macerated denim cotton that has been impregnated with a high-temp phenolic resin. The denim-resin mixture is then formed in close-fitting molds under high heat and temperature until set. TR wheels are non-marking and excellent load carriers, and have higher heat tolerances than their TM counterparts.
