Hello all! This is my first post, and I am just getting into bike repair and such, any info would be great! Here is my issue:
I bought a really nice Motobecane, but I dont think the derailer is compatible with the cassette. Also, the previous owner changed to a mountain bike handlebar and brake configuration (I have no idea what he was thinking...) Anywho, the derailer is a Shimano Tiagra, which according to their site, is a 9-speed derailer. I have a 6-sprocket cassette. If I wanted to get some shifters of the Flite Deck style (brake and shifter in 1) would I have to also get Tiagras to match the derailer? And then also get a 9-speed cassette?
Again, any info would be awesome, thanks!
