One thing that caught me off guard this past week, and may have flown under the average Riv radar, is the new DynaSys shimano shadow detailers. I had one show up that was ordered as a regular shadow. Apparently there was a transition where all being sold as 10 spd are now DynaSys. I am still sorting out the details, but bottom line is that it would neither index nor friction shift across a new shimano 9spd cassette. I have had no problem with earlier generation shadow derailer as well as some labeled DydaSys. I am still not completely sure what has changed, but it was as bad as trying to get a Sram 9spd MTB derailer to work with a retro friction DT shifter.
I pulled it off and put on a regular new 105 GS cage, and it indexed perfectly across all 9 cogs including the 36 tooth one. Apparently there are DynaSys cassettes out there as well with non-uniform spacing between cogs as well, buyer beware Rob.
