bike maintenance question

end of season overhaul time.

I have noticed that one of my rear derailleur pulley wheels is really stiff. Hard to turn it. Also one of my pedals is stiff as well.

Should I be replacing these parts? I worry about the energy lost.

    What brand of each?

    Your pulley should spin relatively freely. Have you taken it apart and lubed it?

    Depending on your pedal, the same should probably apply. I had a frozen speed play one time. Took it in to have it greased and the first mechanic said it was shot. I took it to another shop, the mechanic spent about 2 minutes with a grease gun and it was magically healed. (still riding on it two years later).

    Robin - ultra 6700 di2 on the RD and speed play on the pedals.

    I think that I will take the pedal in and see if someone will work it over. They aint cheap.
    The rd pulleys are cheap so if I can't fix those ill just replace them. I compared them to the pulleys on my road bike and the difference is petty major.
    Now to figure out how to get the pulleys off. This is good though. After IMFL last saturday I promised myself no exercise for two weeks. Taking my bike apart will help!

    removing and cleaning pulleys did the trick. thx!

    Speedplay pedals have a screw on the outside that covers the grease port. Take out the screw and get a small grease gun with a cone fitting and force the grease in. Grease will start coming out around the axle. Keep pumping the grease in until clean grease comes out. Wipe off the grease and replace the screw and see how that goes. I do that several times a year, more if I'm riding outside in the rain.
    I think I'll do that today since I can't remember when I greased my pedals.
    Here's a link to speedplay accessories where you can see the grease gun but you can get a gun like it at a hardware store http://www.speedplay.com/index.cfm?fuseaction=home.merchandise##

    yes please grease your speedplay pedals regularly.

    I don't know about electronic shimano, but for mechanical shimano I always replace the pulleys right away because they are crap.

    you can get more expensive ones but these are good drag/price ratio.
