MDS Chips: 10mm Axle Horizontal Dropout with Updated Eyelet

If you have a Surly frame with MDS dropouts, you can pretty much run most wheels on the market as long as you get the right dropout. This MDS Dropout Chip sets your frame up to be run either single speed or geared like the original Surly mountain frames with a standard 10mm Q/R or bolt-on hub. These MDS dropouts also feature updated fender eyelets with improved positioning over the original models.
