Help identifying rear mech size, please.

Pickled Pig

Can anyone tell from this webpage if the rear mech on the bike is medium or long cage?
Thanks

Do you know what the cassette ratio is - 11/32, 11/34, 11/36, etc? If its an 11/34 or smaller it should be a medium cage, if its a 11/36 its probably a long.

This is all going by Shimano's max tooth capacity for their rear derailleurs... but... the general rule of thumb is/was triple = long, double = medium, single = short

If I had to put money on it i'd say it was medium.

Looks like long in the pic, but you don't say why. Check Shimano tech docs for the correct range for whatever you have or want to do.;

That's a long, why?

Thanks. Cassette is 11-36 so I guess its long, as stated. I've wrecked mine and want to make sure I get the right replacement. I lashed all the docs that came with the bike because I'd never need them

Cassette size doesn't solely define mech size. It's range biggest chainring - smallest + biggest sprocket - smallest. I've got an 11-36 cassette with a tiny caged mech, as I only run a single up front.

As before though, that's a long.

And just look on the mech anyway - it'll say SGS or GS cage somewhere. SGS being long.

will be a long cage since the bike has a triple

Not necessarily. Depends on the range - so a close ratio cassette could make a medium cage ok.

I was not giving an overly long answer TBF - unlikely to get a close ratio cassette on a bog standard bike like that though
