Will combination work? I have 10 speed shifters, 10 speed chain, 10 speed cassette and all components are Shimano.
The reason I ask is because I am new to cycling and I am having trouble indexing my gears. Gears skip and I get some catching. It just might be not indexing properly or it might be the combination.
From a comment:
It’s a road bike but decided to go flat bar initially from a comfort aspect, hence the reason for the Tiagra flatbar shifters - 10 speed. All components are new, frame is second hand, hanger is straight from what I can tell. Cassette is 10 speed Ultegra, derailleur 105 9 speed, chain is a 10 speed SRAM. It’s a mix and I would have gone all 105 10 speed but I bought it aftermarket from a bike shop, and I am only making sense of the components now.
EDIT: Take delivery of the Tiagra RD 4700 tomorrow.Will let everyone know how it goes.
