I had removed the RD 105 5701 RD which has a short cage (distance between pulley centres is 60mm) to accommodate an 11-32 cassette.
Should I re-install it to see if it will?
The RD-5701 is the later version of the 5700 series RD and is rated for 30T low gear, so 32T may be possible.
Not sure if the elliptical ring will make a difference since it causes more movement of the cage and the pulley's possible distance to the cog.
Give it a try... Let us know
