I run 10sp Chorus shifters (labeld Carbon BB system) on Sram Force exact actuation 10sp Fd+Rd on a tiagra 12-28 cassete with KMC 10sp chain.No issues at all,fully functional as basic setup for full use.
Im planning updating on 11sp,and keeping derraileurs,but replacing Shifters with a new 2015 model onwards (Chorus/SR) and an 105 cassete maybe.
Older 11 campag/shimano mixes worked.Newers one?Has anyone tried?
