JSHOUBIKE Bicycle Pulley Bearing Wheel 11T 12T 13T14T15T16T17T Road Bike Guide Wheel for Shimano Sram MTB Jockey Rear Derailleur

As per lower jockey review, this brand is better than all other but with minor flaws. Quality feels closest to the original and it's differentiated the upper and lower jockey. Good enough for the price. The previous set I purchases worked perfectly for my Sora derailleur on the foldie.

The quality of this brand's jockey is better than all of the others ie zitto but still some minor issue like a smaller washer/plate? \nGood enuff for my 11 speed DA mechanical derailleur. No need buy the pricey original ones. Will have to add own grease before install.
