Review on SRAM Apex Rear Derailleur Short: Efficient Shifting Solution for Optimal Performance by Andy Mitts

So easy to install and use. I bought it to use with the 11x32 cassette to climb steeper hills. 15 minutes and I finished and went for a ride.1. old chain removed. Remove the old derailleur with a hex wrench. 3. Install the new rear derailleur using a hex wrench. 4. Install the new chain of the correct size. You can find manuals online. In my case, there was no need to remove links at all5. Adjust the cable tensioner on the rear derailleur so that the shifting action touches all the rings on the cassette and the shifting action is smooth.
