Unless you’ve been living under a rock—in which case: kudos—you’ve likely noticed that bicycle tyres have gotten wider. and in addition to aerodynamic refinements, tyre clearance is one of the primary features highlighted in new bike releases. In fact, many modern road racing frames now have clearance for up to 35 mm tyres—and sometimes more.
Despite this happening for some time now, appropriately wider wheels have not been forthcoming. Over the last few months, that has changed: DT Swiss, Zipp, and now British wheel company Parcours are finally introducing rims that match wider tyres.
