Review on SHIMANO Tourney TY500 7 Speed Derailleur by Brandon Show

You pay for what you get. NG. I've eaten 2 already. Support cage and support wheels deform with normal chain tension. Very weak mechanism. Poorly built. Not worth it at any price. Just a headache. Do not buy! You'll go crazy trying to hire a bad shift! It will always drop gears under load or not shift at all, no matter how good you are at tuning and bikes. Don't waste money and time on it. Have many high and low level switches. This is just Shimano garbage. Yes, Shimano makes "garbage off the shelf". Don't let the Shimano name fool you! Keep in mind.
