New xtr R. derailleurs Q?
I was on the shimano website looking at rear derailleurs and I was wondering what does top normal and low normal shifting mean? Thanks
Top normal means that the derailleur's spring pulls it towards the small cogs (high gear); so when the shifter releases cable, it shifts to a higher gear; when pulling cable it shifts to the larger cogs (low gear). Usually recommended for use with Rapidfire.

Therefore, match the derailleur type with your shifter of choice. As for which type is better, that is subject for another thread!
