🔧 Black X-Wide Box Three Prime 9 Rear Derailleur Review

I bought this with less hassle and high compatibility in mind, but it is not compatible with my Deore switch. No information from the manufacturer.

Shifts well even in muddy conditions. Smooth shifting up to 50T. It should work with the same brand cassette, derailleur and chain, but the price makes it easy. I like having 9 gears with a 12 range. Increased reliability and better shifting at a fraction of the price of a 12 speed setup.

I like the looks and durability but because I ride a lot of rough terrain I like the internal clutch system which keeps the chain from rattling over the stays but most importantly keeps the chain from falling off out! I use this in combination with the trigger switch and it works like a dream! A: Make sure it's set up or entered correctly before discrediting it. But I think it works great for this price so if you're on the fence jump in and give it a try I think you'll see the box is legit.
