The Magura bars have different taper than Renthal bars. You want to use the ones for the Renthal fat bars. The Twin Wall and the Fatbar are the same taper.
Biggs, do you run 30 inch and under bars for our races? If so those won't cut it. If you cut them down like I do there will be no room for the controls.
You could always sell them and slap on some renthal fatbar, pro taper evo's etc...........
