Old Shimano LX rear derailleur pulley
The original pulleys have gone bad on my old Deore LX (RD-M567) and
all the replacements are 10 tooth, this had 11. I tried a 9-speed AEST pulley and shifting is poor. How well would a 10 tooth pulley do? All of the 11 tooth pulleys I see out there are for 9 speed setups. Are 8's made with 11 teeth anymore? Thanks! |

yeah I asked for 8's n the LBS said no 8's only 9's and the 9 was same as the 8 running.
Use red locktite on the bolts. Try sealing bolts with saran wrap for the push thru. UC's review section is cool. "I can feel the difference..." Exquisite. |

Thanks! 11 teeth simply means that the pulley is a larger diameter than one with fewer teeth. Pulley diameter influences two things, the amount of clearance between the lower pulley and the cage, which is a fixed distance while the upper effects the clearance with the cassette cogs. This distance is adjustable, to some extent. -- Cheers, John B. |

But are they the same thickness? 8-speed chains are wider than 9's - will there be extra slop using a 9-speed pulley with an 8-speed chain? |

SLOP: a technical term ?
EXTRA SLOP pig's eat slop! an old wive's tale. new bearings improve chain's run to the next turn. EXTRA SLOP is probo insignificant compared with the new bearing's directional stability Is energy lost ? to tight loses energy, too loose also. one can imagine Shimano engineering discussing the procedures with accounting. All we 8 speeder's are easy to get along with. |

The 9 speed pulleys have some slop with a 9 speed chain, but the same pulleys work equally well with a 10 speed chain. -- Cheers, John B. |

we have a sheet on PULLEY SLOP:
REPLACE when teeth show wear/wheels show excessive cal lateral and vertiplay at bearing surface. Our Guide tells us fancy bearings in pulley cogs give an extremely high cost/effectiveness quotient. Plain bearings well lubed and cleaned/inspected |
