Trek HiFi Deluxe rear derailleur

[cycling51]

Hey everyone,
Does anyone know whether the rear derailleur is a long, med or short gauge. The bike is L and has a 11/36 cassette.

Pretty sure I need a long, but wanted to make sure.

Thanks,

What front chain rings are you running?

It's a 42 32 24 Shimano Dynasys

Thanks,

if it's a triple ring crankset then it's a long..

Yeah I figured it out, but thanks for the reply.
