I'm building up a road bike and have a wheelset with a rear hub that has a Campagnolo Chorus 10 speed cassette. The front derailleur will be a triple and I'm looking into the possibility of using a long arm friction shift Suntour Cyclone GT rear derailleur.
Is there any reason I can't do this? Will the Cyclone have enough adjustment range? Will I need to replace the derailleur cogs with thinner ones for the 10 speed cassette? I've heard the older derailleurs like the Suntour have worked with 9 speed cassettes, and I may respace the Chorus to a 9 as an option.
This is one of many questions I have to ask about this bike build, but thought it best to focus on one question at a time.
