Hello Noob Poster (on this forum) here,
I've got an '05 Hardrock Sport and want to throw on a few inexpensive upgrades.
I bought a Deore RD-M510-L Rear Derailleur and a Deore LX FD-M570 (Top Swing) Front Derailleur on the cheap (Less than $40 for both new). Both components say "Mega 9" Drive Train. Can I use them on my 8 Speed (Acera and Altus Cassette-Shifters) setup without any issues?
