merckx Posted February 12, 2006 Share Posted February 12, 2006 The flat face on the wheel where it goes on the hub to the centre line of the wheel. http://www.usacomp.com/terms.htm On some wheels the offset is marked on the inside somewhere For example ET40 (positive) or ET-20 (negative) Link to comment Share on other sites More sharing options...

garethr Posted February 12, 2006 Share Posted February 12, 2006 Lay the wheel face down on a flat surface, lay a straightedge across the rim, measure the width of the rim and divide it by 2. Measure from the straightedge on the back of the rim to the mounting face which fits against the hub. Subtract one measurement from the other. You are calculating the distance that the mounting face is offset from the centre-line of the wheel. You could take the same measurements with the tyre on the rim, although it might be a little less accurate. Link to comment Share on other sites More sharing options...
