SRAM Force/Rival/Apex 10 Speed Rear Derailleur Pulley Set

Purchased these to replace the existing pulleys on my Sram Red derailleur after identifying a radial crack. There are two differences between these and the red version. The red have ceramic bearings and the pulleys have cut-outs to further make them lighter. Unless you are really concerned about weight, functionality is identical. In addition, the old pulleys cracked right at the cut-outs so I expect these to be less prone to cracking. Note: If your old ceramic bearings are still good you can always swap them out.

As I was going through my bicycle (2010 Pinarello FP2 with SRAM Rival groupset) I noticed the old derailleaur pulleys were both cracked. These are a perfect replacement.I was reading it's not that uncommon since the pully is plastic and it appears SRAM changed the design slightly maybe to address the issue.Installation is super simple but make sure you check the positioning as they are directional.

Shifting seems a bit better. One less thing to consider in a 12 year old, ~10k mile bike.

Works great with SRAM Red 10 speed derailleur. Much cheaper than the $100 Red wheels and roll just as good.

replaced my cracked derailler sprockets to make it like new.

Fit SRAM Red one pully needed to use the old spacers as per other review here.

Product fit perfect works great

The ones I received were in SRAM OEM packaging. As others have stated, these are a perfect low cost replacement for 2012 SRAM Red. Just be sure to keep your existing bolts and washers (washers are not the same ID). Replace cracked pulleys at a fraction of the ceramic red cost, and no difference in shifting performance.
