Jockey Wheels 11T/11T CERAMIC - 6mm wide Duraace RD-R9250 Specific

Superstar Components UK Made derailleur wheels have been specially developed for Shimano Duraace RD-R9250/R9270 for their unique ultra narrow 6mm width. They are manufactured in the UK from high-strength Aerospace grade 7075 T651 aluminium alloy. The tooth profile 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 deep groove ball bearings with precision ceramic balls 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 visible rust the bearing is contaminated and will die no matter what the material is!)
