Shimano SLX M675 10 SPD Rear Derailleur

Featuring Shimano’s Shadow Plus technology and a new chain management system, the M675 rear derailleur provides precise and crisp shifting while minimizing chain slap and reducing the chance of dropping the chain. Shadow Plus technology also makes rear wheel changes easier thanks to a clutch toggle switch that allows you to lock the M675 in an open position. In order to provide more protection from rock strikes and other obstacles, the M675 rear derailleur has a lower profile and is compatible with direct mount derailleur hangers

Shimano SLX Rear Derailleur
This product was bought for a friend. I bought it based on people's reviews on its durability, performance, and its price.

Initial impressions: well packaged, box wasn't crushed. The derailleur arrived without any defects.

I live near Jenson USA, the package was delivered in a fast two days.

I installed it on a race bike (Ridley Blast A9) that was being built at the time. The shifting is very comparable to XT, with the exception of weight and sealed bearing pulleys. The for the price, it's features are worth the buy.

It is paired with Deore shift levers, a SRAM PG 1030 cassette, and a KMC x10.93 chain. I plan to get an SLX cassette so the system works a bit more smoothly. For now, it works just fine.

It's been ridden more than 100 miles now and it still runs like new. The clutch needed adjustment after 50 miles (yes, it can be adjusted).

I highly recommend this derailleur for its performance and attractive price.

Just Awesome
This thing is awesome. The clutch nearly eliminates chain slack. The shifting is extremely crisp. It was very easy to setup and dial in. I was able to convert from a 3x8 to a 1x10 and eliminate the front mechanics. I feakin love this derailleur.

CONS: NONE

I would buy this again
Bought this when I converted to a 1x drivetrain. I've been really pleased with this mech, actually I find I don't need to use the clutch all that often as the chain is kept really tight. Great shifting, good product.

PROS: Durable, Crisp shifting

Decent product
It has very precise shifting, but if it's the least bit cold, you can't use the clutch. It doesn't shift back up when the clutch is on and it's cold.

PROS: Durable, Lightweight, Attractive Design, Easy To Install

BEST USES: Racing, Mountain Biking, Upgrade, Casual Riding

Reliability and value
Solid 10sp performance delivers great value. I have this derailleur on three 1x10 bikes and they all get the job done.

Queit ride!
The clutch has eliminated chain slap. I run a chain watcher on a 1x10 but I don't even think it is necessary with the tension I get on my chain.

Great Derailleur
I live this RD. I'm running it on a 1x10 drive with a Race Face wide/narrow chain ring. The clutch is great and eliminates chain slap and drops. It shifts crisp and appears to be well built.

Is it compatible with traditional derailleur hanger?
A shopper on Jan 5, 2017
BEST ANSWER: As has been brought up it will fit. Be careful of the freewheel or cassette selection as these derailers sit very close to the cassettes and can interfere with the chain going from sprocket to sprocket. I have an XT Shadow Plus, same overall design, running a Mega range 7 speed cassette with no problems whatsoever. I have a Deore Shadow Plus MTB derailer mounted on a 1980 road bicycle with a bolt on derailer hanger and it works great with a 10 sp 11-34t cassette, also friction shifted. Both of these derailers are like the SLX in design and configeration. Good luck.
