      Wore out the plastic Shimanos and got these. Seem to not spin as freely as the plastic jockey wheels, but don't notice once installed.

        Great product - well worth the additional cost to have them shipped from Jensen. Bearings are silky smooth. Noticed an immediate improvement in shifting performance and power transfer. Plus they look great!

          Comments about KCNC Bike KCNC Ultra Derailleur Pulley Wheel:

          Yes, you save a few grams, and they will likely outlast OEM pulley wheels, but with accent colors and uber cool CNC machining these are like jewelry on a beautiful bike. No they are not necessary but they look soooo good.

            Got the blue, it's a nice colour. Spins with little friction. Extremely easy to swap pulleys since it has sealed barrings. Doesn't seem to attract as much dirt as the plastic ones.

              Great item, lower priced than OEM and probably stronger/more durable (have not used it long enough to compare). 7075 aluminum vs OEM plastic (SRAM). Sealed bearings.

                Great product, easy to install. Noticed the difference right away. Quick delivery by JensonUSA. Picked the RED color, looks good. At this point can not comment on durability but my guess is they will stand up to heavy use

                    Super smooth! Makes a cool sound as the chains runs over them. They also don't seem to attract dirt like the nylon stock pulleys.
