So that's a Short cage and will only be able to handle a cassette up to 28t . based on the derailleur hanger design I'd rule out a range extender. Those soft pewter hangers bend easily and the extender will put a lot of leverage on the hanger. 50-34 front 11-28 rear is your best bet. I run 50-34 F and 11-25 rear cassette on my lightweight bike while my aero bike uses 52/38 11-28. The 50/34 11-25 combo gives me much lower bottom range than I need for Signal hill. With a 11-28 on the back can spin easily up that climb. MTBRIDER1234 and Abel Du Plessis 1 1 Link to comment Share on other sites More sharing options...
Fat Boab Posted June 10, 2022 Share A couple of additions to the excellent advice so far: 1. Look up the specs for the RD part number. 2. The largest sprocket value from the spec should be considered a conservative guideline (ie often you can shift larger sprockets than the spec with no problems...but not always. I shift +2 over my RD max spec with no issues whatsoever.) 3. Overcoming a shifting issue from 2 above can include an RD extender and/or B screw manipulation, new longer B screw or even reversing the B screw. Plenty more on this on the web. Lots of hacks around if a 34-28 granny gear isn't big enough! Abel Du Plessis and MTBRIDER1234 1 1 Link to comment Share on other sites More sharing options...
NotSoBigBen Posted June 11, 2022 Share I'm a 'tinkerer' so I also, as some here have alluded to, think that sometimes you just have to try something out despite what the specs say ... By all accounts this probably shouldn't work but it does, an old probably 9sp I'm not even 100% sure road derailleur with an 11-36 cassette. Yes it doesn't shift super crisp as some want but it shifts OK for me. Having said that it's also not the kind of thing you should expect or demand that your local bike shop does and then want it to be perfect! It's on you and you alone if you decide to do this kind of Heath Robinson cheap ass solution 🤪 Abel Du Plessis and Mongoose! 2 Link to comment Share on other sites More sharing options...

It looks to have a medium length cage so maybe a touring unit ? Link to comment Share on other sites More sharing options...
