I'm making slow progress on a 55cm Cheviot build for my wife and am hung up on determining the proper chain length. The Riv website says:
>The chain is the right length when it pulls the derailer cage free of and parallel to the chain itself when wrapped around the smallest cog and the smallest chainring -- i.e., the derailer cage will be flexed slightly. Try as I might, I'm having a hard time visualizing what this means - can anyone unpack this further for me? A picture would be even better! (The there's also Sheldon's rule of thumb calling for one full link of overlap when the chain is wound around the large-large chainring/sprocket combo, but I'd still like to understand the Riv method). I'm also a a little stuck on front derailer options. I'm setting this up with the Silver wide-low double (38x24 with chainguard) and the front derailers I have on hand (IRD Alpina-f, Suntour XC-9000) both have a lot of daylight between the bottom of the cage and the chainguard. It looks funny, but would it affect performance? I'm open to buying a new part if needed, but am getting a bit Marie Kondo and would rather declutter my parts stash than add to it.
