Superstar Components UK Made derailleur wheels have been specially developed for the SRAM EAGLE drive system. They are manufactured inhouse in our CNC facility in Lincoln-UK from high-strength Aerospace grade 7075 T651 aluminium alloy. The Narrow / Wide design of the wheels keeps your chain safely where it belongs, and also provides a crisp shifting behaviour. We know our customers ride in extreme conditions so we fit double sealed bearings which are replaceable in-case they wear. These are further hidden by a double labyrinth seal for extra durability.
In order to ensure the smoothest possible running over a longest period, we install standard size sealed deep groove ball bearings with the option of ceramic hybrid bearings for extra performance. We do not fit stainless steel bearings as they are softer than bearing steel and will fail much sooner than a bearing steel will rust. (if there is visable rust the bearing is contaminated and will die no matter what the material is!)

Standard bearings come with black shields, Ceramic bearing with red shields. if you want different colour then spares are available HERE

Quality of the product is amazing but the jockeys will go out of sync with the chain when under a hard impact or whenever your chain slaps about. You have to stop and pull your derailleur every time you want to sort it out.
Superstar Comment: This can only happen if all the load comes off the chain and then a load of slack ontop which can only really happen if the mech is setup in
