12X27 instead of a 12X25? Will that work
I just bought a new set of wheels and I need a rear cassette as well. I'm looking at the 12X27 Ultegra cassette for these rims. My question is, if I have a 12-25 on my stock rims and switch to a 12-27, will I have to adjust my rear derailer everytime I swap my rims out? I plan on using my old rims on my trainer.
