SHIMANOGuide pulley + tension RD -6700

I noticed a cracked derailleur pulley on a road bike I had purchased around 2009. Not wanting to replace the entire rear derailleur (which worked perfectly fine) I looked for a pulley set that would be compatible with both my Shimano Ultegra derailleur and my 9 speed rear cassette. This pulley set worked perfectly. After watching a couple of YouTube videos showing how to replace the pulleys, I was able to successfully complete this task without any undue difficulty. A word of caution, however. Pay attention when you replace the chain that it flows through the bottom pulley correctly. I did not do this which resulted in having to take off the bottom pulley and reattach it after correctly placing the chain through the pulleys. Not doing this correctly the first time turned a 15 minute job into one that took 30 minutes.

Perfect replacement pulleys.

Exactly what I needed. Shipped quickly.

Ordered from this seller before and an order got lost, contacted them and they promptly got my order to me.These cost more than the bushing style, one is ceramic and one sealed bearing. The ceramic has rubber gaskets on metal washer. They weren't on my original, probably dried up and fell off. Others have stated there is some resistance or drag on the ceramic pulley. It is due to these rubber bushings, if you leave them off it will free spin but you have some side to side slop. I tried both ways and put them in.If you want to leave the rubbers out, add a Stainless washer to both sides. I'm sure I'll be doing that once the rubbers disintegrate.Pay attention to rotation and location of each of your old ones. Ceramic bearing is top location on mine. I'm sure ceramic would not withstand the punishment on the bottom cog. Lots of different angles when shifting and bottom takes the licks on trail. Was good factory replacement for my Deore 9 speed deraileur. For a 23 year old deraileur it works like new after clean up and installing these pulleys. I could have just kept old ones as they really were not bad, but good to have spares.These NYC dudes have good prices and are very responsive. I get need for more parts I'll be looking them up. Must have a good business up yonder in that congested city with plenty of riders needing parts.FIVE STARS!

They work well, but include questionable value proposition of OEM Shimano parts. Expensive for what you get. In this case, its a utility bike and I was trying to fix a shifting problem. I knew these parts would fit and work as required.

They mount very easy. Pulleys are labled so they can be installed correctly. Great price!!

I did not expect to have to take these off and lubricate them but I did after a few dry mountain bike rides. I'm not sure which one, upper or lower, but I put lithium grease on both. Disappointed.

Exactly what I was looking for, match for the original pullies

As expected very happy with product, thank-you.
