Solid! Replaced Tiagra
This derailleur is an excellent value at $60!Replaced my worn Tiagra unit and quite literally it’s night and day. It made the lever action a bit more firm which I like.Just got done riding 500 miles of gravel across Iowa and didn’t miss a shift!

Great upgrade from tiagra 10 speed
Works great with tiagra 10 speed shifters and an 11-36 cassette. Hills are much easier with the max 36t. Have heard it can go bigger with a goat link as well

Stellar rear derailleur at a sweet price point
Could not locate 10 speed long cage replacement for old Dura Ace on a Trek 5500 road bike. When I put a new cassette on, I increased cog count and original short cage derailleur could not accommodate 30 tooth sprocket. Opted for GRX as I have the 11-speed on my gravel bike and it works well. Install and setup went well, just need less snow to test under real world loaded conditions. Happy with purchase and value.
