Manufacturer Part Number Discrepancy
11 Jul 2015
Your website shows this as Manufacture Part number as Y6PZ98050, but isn't the product displayed actually Y6PZ98080 or Y6PZ98090 ? I am looking to buy one of each (80 & 90). Please can you advise /send me links to both as I need a RH and LH.

This is the correct part for fitting to a SL-M660-10 shifter which is the 10spd version, the two part numbers you have give me are for the 9spd shifter which is just SL-M660. The parts you are looking for are available form us and are our part numbers 34644 and 34643.
