In yesterday's race, the chain hopped off the bottom pulley of my rear deraileur like five times. At best, it was a pain. At worst, it sucked into the deraileur into the wheel making an awful spokes in a woodchipper noise (luckily, I broke no spokes).
Since the derailleur is an old RX-100 out of the junk box, I've decided it's ready for retirement. The only question now is way to replace it with? Do you guys run MTB or road equipment on the back end of your drive train? What are some of the weird cross-compatibility issues you've run into? Right now I'm running an 8-speed 11 - 23 hyperglide cassette on the back. I'm using 8-speed shimano barcon shifters set on friction.
I was thinking of replacing with an LX or DEORE rear deraileur. Any thoughts / tips?
