I am just a leisurely rider and wanted to ride to get a little more exercise besides walking. I recently purchased a used 24” Electra Cruiser 7 and I love it! I would like to replace my derailleur and the cassette or flywheel once I figure out which type I have. I know I have a Revoshift SL-RS35 7 Speed Right Side Shifter and a Shimano Tourney 7 Speed Rear Derailleur RD TY300 but I don’t know if I have a freewheel or cassette or what type of chain I have. I like to diy whenever I can because I’m retired and on a fixed budget. So any help would be greatly appreciated. Thanks for reading my long intro. LOL
Awesome!
I lived in San Diego when I was a kid, La Jolla, in fact. My brother and I used to bomb around the canyons on our Raleigh Rampar BMX bikes (this was late-70s), I think I remember riding my bike to school sometimes but man, some of those hills were BRUTAL! Definitely paper-boyed my way up a few of those.
My bro just moved down to SD from the Sonoma area. His cycling reports leave me super jealous (although his $5k MTB getting stolen from his condo's 'secure bike storage' wasn't so great....)
I don't know your particular bike but I'm pretty sure it uses a standard Shimano cassette and SIS index chain. That's a long-cage rear derailleur, so it should handle a wide spread of gears, but you're still limited to seven speeds at the back. I find when I'm exploring product ranges new to me, it's best to ask at a couple of local bike shops, just to avoid expensive mistaken purchases.
One other thing to note: technically, you should be free to mix Shimano and SRAM cassettes and chains. However, though long-change derailleurs let you run a wider spread of gears at the back, the gear shifts tend to be less 'snappy' than you get with a short-cage derailleur. If you, say, throw a SRAM cassette on there, it's possible that you'll end up with less-satisfactory shifting. It's not necessarily a problem but it's worth bearing in mind.
One final, final note (honest): in future, you might get faster responses to wrenching/technical questions in
the Repairs and Mechanics 'room' here.
I hope that helps. Feel free to post more posers and happy riding!
