As I have mentioned before I put on the 26" upgrade on my Terratrike. The main reason was to get the RD and chain further up out of the dirt. In some gears the RD tension wheel and chain are not much more than an inch off the ground with a 20" rear wheel. Being that low it just has to pick up a lot of dirt and grit and cause power train wear.
And yes I did change the rear cluster to 11-34.
