Great replacement
Nice and smooth operation on my a Trek Marlin 4. Once installed I was worried the big wheel would need more chain but it worked just fine.

It’s smooth and works well.
Installed on my son’s bike after he trashed the last one. Shifts just fine no problems.

Sleeper derailleur
This is a sleeper derailleur, I recommend you go to Rivendell bikes page and read their description. With a waxed chain and proper adjustment this shifts perfectly. I’m almost considering replacing my higher end shimano with one of these because of the size, tooth count, and exceptional function.
