MPC has emerged in the last two years as one of the top , if not the top maker of wheels for outdoor track skating. This year, the U.S. wheel maker hopes to extend its success to road skating — and it's off to a fast start. Skating on MPC's new VT 100mm wheels, veteran racer Diego Rosero destroyed a world-class field at the Pre Worlds marathon two weeks ago in Cartagena, Colombia.
   The 26-year-old Colombian finished nearly three minutes ahead of second place Joey Mantia, the reigning world marathon champion, and third-place Massimiliano Presti, the reigning World Inline Cup champion.
