Shimano Saint RD-M810 Rear Derailleur $0.00
The Saint RD-M810 Rear Derailleur packs the same legendary durability you expect from this premium Shimano line with a lower weight and low-profile design. While the Saint Derailleur weights only 250g, it uses Shamano’s Shadow technology to reduce the chances of getting clipped on a rock or stump. Unique design characteristics let you run road or full MTB cassettes with the same cage. Plus, you get the precise one-click shifting you demand for your ride.
Reviews & Community
I'm generally a fan of Shimano and LOVE the idea behind the Saint line. This was my first saint product. I mainly ride up logging roads and bomb down single track- wouldn't consider myself a downhiller but I do ride moderate to hard. I had this derailleur setup on a mojo SL with a freeride build up. I don't remember hitting anything with the derailleur but I noticed some clunky shifting a couple weeks ago, after trying to realign it I realized the derailleur itself was bent. My hangar dropout hadn't moved at all. The thing didn't last a season, I feel the hanger should have bent before the derailleur, especially it being marketed as "tough". Looking at replacement options now and don't think I'll be going with Saint again...

Will this work w/ any 1-click shifter? Say a SRAM X.7 or 9?
Write your answer here...n o Sram actuates at a different ratio than shitmono.
I was getting too much chain bounce on downhills on my AM bike (Trek Remedy). This replaced my stock XT long cage. The long cage Saint derailleur has a shorter arm than the XT long cage, maybe a little longer than an XT med cage.
The super stiff spring means less chain bounce; and this derailleur really tucks itself out of the way of rocks and logs.

Do you need a 9 gear cassette? Or will it work with an 8 gear cassette?
It will work with an 8 spd as long as you have 8 spd Shifters, Cassette, and Chain

Got good price, quick shipping from Huck N Roll .. replace the Sram on my Specialized SJ, quick and easy changing speed on this derailleur
Stout and tough
This derailleur is tough! Regardless of what is has run into, it continues to WOW me! It is way lighter and easier to use (wheel changes) than the old style which mounted to the axle. This derailluer has an amazingly stiff spring in it which provides super fast shifts. Seriously, who backs their parts with a 3 year warranty if they do not expect them to last. A full year on my DH bike and it shifts like new. I will be running the same one next year probably!
Does this mount to the frame or the hub...
Does this mount to the frame or the hub like the old saint derailleur?
Shimano has gone away from the Old Axle Mounting system and now mounts their Saint Rear Der to the Der Hanger.
This derailleur has the stiffest spring known to man. The first time I used it I couldn't believe how crazy fast downshifts were. The looks alone are what got me from the start, love em'. I still don't know if I like it as much as my SRAM X.O. but that's definitely personal preference. For the money you cannot beat this as one of the best DH derailleur's on the market.
