I have a Novara Hybrib I want to upgrade all the drivetrain components Seeing all the choices out there, where do I start? Are there full sets from manufactures or how do I tell if individual parts work together? Any suggestions are appreciated Thanks

I recently upgraded the drivetrain on my recumbent. I bought matched cassette, chain and derailleur from SRAM. I waas amazed at how well matched components work together. Keep this in mind in your final decision. bk
