Anyone tried this before? I wanted to move the spring tension to the stronger option after using if for 1 year, but was unable to do so.

In the 2010 RD, this is possible after removing the aluminium cage stop screw on the pulley cage and rotating the pulley past the hole. Also the 2011 and 2012 shaft looks different as shown in this post Sram X0 rear derailleur rebuild . Any ideas?

Thanks!
