    Fitting Shimano/SRAM cassette

    I know the basic principles behind removing/installing Shimano or SRAM cassettes on a normal splined freehub. Just a couple of questions.

    1. When fitting a new cassette, where should I apply grease? On the lockring I guess, but also on the splines/body of the freehub? Anywhere else? Is normal lithium grease ok?

    2. How can I judge the correct tightness for the lockring without a torque wrench?

    3. Is it better to remove cassettes by placing the removal tool in a vice and turning the chainwhip, or stand the wheel upright?

    4. Are SRAM Powergilde PG-950 and PG-970 cassettes fully compatible with Shimano 9 sp chains and derailleurs?

    Thanks

    1. Grease the lockring threads. Maybe a thin smear on steel freehub bodies but I don't bother on alu.

    2. When the ribs on the underside of the lockring engage, you'd be able to feel/hear clicks, I normally count about 4 or 5 which is snug but not super tight.

    3. I just use a 10" adjustable wrench on the spline tool. Never needed a vice.

    4. Yes. I prefer SRAM cassettes on my mountain bikes - shifts just fine with Shimano rapidfire and seems lighter and longer lasting. BTW also recommend SRAM/SACHS chain.

    A little grease on the lockring threads.Always a good idea on threaded stuff. Turn the lockring fingerthght with the lockring tool,then give it about another 1/4 turn using a wrench. No need for a vice with a lockring. They are compatible.

    Thanks.

    That Park link is useful but doesn't discuss in detail where to grease etc.

    BTW also recommend SRAM/SACHS chain.
    Yeah, I hate Shimano chains... Powerlink much better than their crappy oversize pin system.

    No point to smearing grease on the hub body.

    Really? So there is no danger of the cassette seizing onto the freehub?

    Where exactly should I grease?

    Put a SMALL amount of grease on the threads of the lockring. That's it.

    If I want to change the cassette from Shimano to Sram, do I have to change the freewheel etc. of will the sram cassette just fit on the wheel over the old simano freewheel without any problems

    Thanks

    I'm pretty sure Shimano and SRAM cassettes are fully interchangeable...

    It will fit fine over the freeHUB SRAM cassettes are made to be fully swappable with Shi*No cassettes on Shi*No compatible freeHUBS http://www.sheldonbrown.com/free-k7.html
