Halfords reported a 7.8 percent growth in retail cycling sales in the 15-week period ended Jan. 12, despite the difficult U.K. retail environment. The growth was driven by retail sales across all bicycle categories, cycle repair and PACs. Halford Group's overall revenues increased by 3.2 percent in the quarter. The company said it expects the U.K. retail sales environment to remain subdued during the fourth quarter and the full year 2018.
