Cannondale FS-i conversion from 1x11 to 2x10

Recommended Posts

Hi,
I need some help with a set up for a Cannondale FS-i Carbon Factory Racing 29er (Ai)
The bike has a 1x11 set up and I wish to change to a 2x10 set up. I have the rear mech & shifters but would like to know what parts & part numbers are needed from Cannondale?
i.e. front mech mounting plate and type of front mech (down swing / side swing)
Also which part for the crank spider.... (the chainrings are Truvativ x-Glide 39T 10spd 120 BCD & 26T)
P.S. I also have a 10 speed cassette for the rear wheel & freehub body
Thank you

Hi there,

1. You probably need the down swing (or high clamp) rear derailleur. Explanation here:

 

2. Then you need the KP350 front mech adaptor (picture below). 

3. The freehub will accommodate 10s cassette, but most likely you need a spacer for that.

4. As for the crankset, I'm not sure, whether you can simply swap the chainrings, or you need to buy a whole 2x, Ai specific cranks.
