Greatly appreciate the replies!
So are the FM-909 and FM-936 basically the same frame geometry, just different weights, or am I missing some other aspects that makes these frames different?
Geo looks the same. 936 is a rocker link vs the swing link of the 909, so the 909 has 2 bottle mounts in the front triangle. Looks like the 909 has shorter seat tubes than the same size 936 as well. 909 has mounts for a chain retention device. Seat tube diameter is diff too.
Thanks! I don't know enough to understand the tradeoffs between rocker vs swing (other than room for 2 water bottles). If there is a link to a good explanation would like to learn.
