It is listed at 80mm and given as 78mm on the data sheet, with a 20mm half-round groove for 20mm round bar. Two foot flanges, 136mm long overall with 8mm holes at 110mm centres, bolt up to the underside of the rail, and just 27mm of the wheel shows below the mounting face. The price shown is for one wheel with its bracket, with a minimum order of 6.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e This wheel runs on 20mm diameter round bar track only.
