My cheap bike that I use to commute has been taking a lot of punishment (mostly from salt that's been used to melt the snow). I've been thinking about changing the rear derailleur (maybe not right now, but for the summer), but I'm not sure what replacement part to get. My bike has a 6 speed 14-28T cassette.
This is a picture of my derailleur. I think it's a direct mount, so I was thinking about substituting it with the Shimano TX-35 Rear Derailleur Direct Mount.
And this is the replacement part that I'm thinking of buying.
Would the replacement part work, or do I need one with a hanger?
Thank you very much everyone.
