Importance in Bicycle Making
Accles and Pollock was Britain's other lightweight bicycle tubing manufacturer, competing with the more famous Reynolds Tube Co.
Many leading bike builders in the UK during the 1930s, '40s and '50s, preferred to use Accles and Pollock tubing as it was air hardening, unlike the manganese-based Reynolds product which was not. Air-hardening tube-sets actually become stronger when brazed, unlike the normal steel tubing sets, such as 531, which are weakened by heating. Air hardening products were not introduced by Reynolds until well into the late '90s, and are now being marketed to cyclists as the latest thing in steel. Accles and Pollock's Kromo tubing was used by Hobbs of Barbican, Rattrays of Glasgow "The Flying Scot" and Thanet in their "Silverlight" model.
