After I got the 18 inch tubeless build with the stock gearing supersprox, I have had my share of chain slap. I have adjusted the chain loos ( about 5cm as per manual), and tight at 3cm....... 2mm camber left...... 2mm camber right.... And nothing seems to help. Have had non of this before the new wheel. Excel 18 inch tubeless....supersprox. A fantastic combo..... Chain is the stock installed after the recall. Had 1500 miles from new when I changed the wheel. I know about needing to change it all, when installing a new sprocket, but through out my life on bikes.... I never had this. It happens at neutral torque, on the bottom 1/3 of the chain. Drives me nuts. Next is a new DID chain with a master link. I was just curious, if any have had this happen after the taller 18 inch rear....???
