Hi, I’m interested in converting my 2 speed C-line into a 3 speed to get one more gear and to tweak the gearing. I was hoping someone could just confirm my shopping list is correct for what I need to do the conversion. Suggestions are definitely welcome if you think there are better parts for the job.
​
**Microshift Friction Shifter**. This seems like the best friction shifter I can currently get. If anyone knows one they think is of better quality, let me know.

**Shimano 105 11 Speed Cassette**. I know people do this conversion with a 10 speed cassette. Not sure how the difference will affect it in the end. I have a 50t chainring. Might change to 54. 12-25 cassette (12-13-14-15-16-17-18-19-21-23-25)

**KMC X11 Chain**.

Thanks for the help!
