It turns out that not many derailleurs in this price range will allow for a larger 32T cog and 37T capacity! I'm running this with an old school 7speed downtube shifter, 11-32T Tiagra 4600 cassette and Tiagra 4601 chain and it's smooth as butter. Many gear combos are totally silent. Shifting is smooth even under load. Very happy with this upgrade from old 9spd 12-25T. Highly recommend this if you are looking to fit a cassette with cogs > 30T.
This Medium size rear mech was ordered to replace a small version originally fitted to my bike. Fitting a different larger mech was a gamble but it paid off. With some wide ratios [50/34 front and 11-34 rear] the shifting is now much more crisp and precise . A good buy!
Easy to fit, looks good, easy to tune.
