Shout about this product!


Superstar Components UK Made derailleur wheels have been specially developed for the SRAM XX1 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!)

Pack Includes - 2x 12T jockeywheels with bearing shields
Standard bearings come with black shields, Ceramic bearing with red shields. if you want a different colour then spares are available. *Please note*: some Sram rear mechs use a larger diameter bolt hole on the top wheel. If your mech is as described, you will need to purchase the Sram covers also. They can be found on the link --> HERE

These jockey wheels are suitable for newer SRAM and rear derailleurs, which are 11-speed compatible. Not suitable for SRAM derailleurs with integrated roller holders (2-point mount). A small number of models of road derailleurs from SRAM (such as some SRAM Red for example) have an upper roller with a 4mm screw mount rather than normal 5mm diameter. A reducer sleeve is available for minimal cost online from Hope, we are not manufacturing this part due to minimal demand.

    Great replacement for the crap plastic ones that came with my Sram NX 11 speed. Nice colour, no extra noise vs the plastic ones, good bearings. shifting perfectly after a few months of use.

    Bought these to replace the standard one on a sram GX mtb derailleur. After 3 years of abuse, the standard ones had had enough. These are super smooth and do the job effectively. Excellent. Happy me.

    Arrived today and fitted straight into derailleur. Like jewellery! Be careful to get the teeth into the correct spaces in your chain (thick and thin teeth, like a chain wheel) or the chain jumps and you think you've bought the wrong ones....

    These arrived today and fitted straight into my SRAM Rival derailleur without needing spacers (on Sonder Camino gravel/adventure bike). As with other Superstar components I've bought they look to be very well built.
