Seems like a 10s chain is nearing the limit of physical integration given the number of things it has to play nice with in a 7-8s drivetrain. RD jockey wheels, each cog of the cassette and the chainring. Dysfunction would seem less likely if all the rear parts were of the same spec and the single chainring was the outlier.
Did the replacement jockey wheels leave the top one with some movement left and right on its axle? Shimano RDs have that to allow the wheel to fine-tune itself after the chain has been moved from one cog to another so the shifter adjustment (or you if in friction mode) don't have to be perfectly accurate. The RD wheels will really make noise and want to auto shift thanks to all the ramps and such with little provocation. Be sure the slop's in that top pulley wheel. On my Rambouillet I only use friction mode for 8 cogs and have found that the RDFs that have no side to side play by design work really well for me and I go between Suntour XC Pro and a Mavic 841 for that crispness but manageable at 7 or 8 speeds with a friction bar end shifter. Andy Cheatham Pittsburgh Shimano 7s HG cogs are 1.85mm thick, the 8s HG is 1.8mm, 9s is 1.78mm and 10s is 1.6mm. Shimano 7s chain width is 7.3mm, 8s is 8.1mm, 9s is 6.6 to 6.8mm, 10s is 6.2mm and 10s narrow (CN-5700,CN-6700,CN-7900) are 5.88mm. None of that addresses the actual width of the roller or inside dimension of inner plate spacing which seems where the absoluteness of fit/no fit really is demonstrated. Some steps in higher number speed drivetrains are well documented to not change that inner dimension like 9 to 10s where reduction of material outside of the roller thickness reduces the outside width. Leonard Zinn answers several questions from readers about the interplay of mixed speed components here, the description of mechanical dysfunction he provides seems really pertinent: Velo News-chain compatibility <http://www.velonews.com/2016/01/bikes-and-tech/technical-faq/tech-faq-chain-width-explained-compatibility-queries-answered_392163> On Saturday, December 3, 2016 at 4:16:00 PM UTC-5, Eric Karnes wrote: > > Hi all- > > I was wondering if I could pick your brain a bit on this.
