Great value in a 9 speed rear derailleur from Shimano. The Deore 510 handles up to a 34 tooth rear cog and uses flourine coated bushings, reducing link pin friction for reduced shifting effort.

Special 11-tooth pulley design means alternating contact between chain links, reducing wear and allowing the chain to run in a smoother manner. Aluminum and stainless steel construction keeps the derailleur lightweight and durable.

Weight: 300 grams
Compatibility: 9 speed drivetrains
Feature: 11 tooth pulleys

      I am currently running this derailleur on my second bike and am very happy with it. The shifting may not be as crisp as with something like XTR or XO but overall I cant complain. I've also ran this on my DH bike in the past and it worked well and the nice thing was that I wasn't worried about trashing it as it doesn't cost a crazy amount to replace. I've rode it in dry, wet and snowy conditions and it works well in all of them.
      Overall I am very happy and would recommend this product. Cant beat Shimano quality and the price is great too

      I would not buy it for downhilling or jumping, but freeriding with it is just fine. I would rather get the Shimano XRC... that is more expensive but a better build part.

            Smooth shifting

            By Menahem Yachad

            from Jerusalem Israel

            Verified Reviewer

            After about 15 years with my original STX-RC derailleur, I had to replace it. Now 15 years is along time for a derailleur to last, and if Shimano had still been making them, I wouldn't have hesitated. After a lot of research, I settled on the Deore. Great value, and solidly built to last. Weight is not a big consideration for me - a few grams heavier than the XT part is just fine. Deore is solid and smooth.

            Great for a functional, riding bike that needs to work every day. will handle full range of front and rear gear sizes. Just works.

            The bottom line is...

            By John

            from Tucson, Az

            The bottom line is that this is a comfort bike level derailleur and is not appropriate for anyone who really wants/needs to be confident in the shifting action. As I stated before, this is going on my girlfriend's mountain bike. It'll be a good beginner/light use piece for sure, especially considering the price.I would give it a one star if it was over twenty bucks.

            no problems. its being used on a trail bike so not to important to be Uber light. not quite race worthy though. get an XT if your racing
