    Is there such a thing and where can I obtain one? I have an old set of wheels that would be nice to
    use, and I would if I could thread an 8 speed freewheel on there. Thanks!

    Definitely yes. Try rec.bicycles.marketplace, eBay, etc. Sachs/SRAM used to make them, but not any
    more. They do turn up regularly.

    There are several reasons why you don't want this freewheel -

    1. You will probably need to respace the hub and redish the wheel to allow the freewheel to fit. The
    increased dish will make the wheel weaker.

    2. You will increase the likelihood of a bent rear axle after respacing it. This is a common problem
    with 8-speed freewheels.

    3. You can use a 7-speed freewheel instead - spacing is nearly identical to 8, will work with
    8-speed index systems, last click in the shifter will be unused.

    The best 7-speed freewheel is Dura Ace. Also no longer manufactured but still available if you have
    plenty of $$.

    Best long-term fix is to rebuild the wheel with a cassette hub. If you match the hub dimensions
    fairly closely, you can replace only the hub & cogs, reusing the rim and spokes. I use new nipples
    when I reuse old spokes; the spokes themselves do not need replacing unless damaged.

    Yes, Sachs used to make them... and you don't want one.

    Using any freewheel with over seven cogs is just asking for a broken axle.

    You'll need a Campy 130mm axle and I'd recommend it only for riders under 160 pounds. It IS a strain
    on the axle.

    I've had exactly the opposite experience.

    I've got one with a 135mm axle for my touring frame. I weigh in at about 170lb, and my bike loaded
    with gear is about 90-110, depending on food/water.

    Never had a problem with an axle, and I've ridden it cross-USA, up the Alaska hiway, out to Jasper,
    down to Mexico, etc...

    SRAM make several - you can buy these from Nashbar - http://www.nashbar.com A. E. Bike also has a
    couple from the QBP catalog - http://aebike.com/site/page.cfm?PageID=30&Category=531

    Or you can build your own - get a cheap Shimano HG-37 14-28 seven-speed freewheel and replace
    the lockring with a 13T screw-on sprocket from an old DuraAce or Shimano 600 uniglide freewheel.
    If you're really picky you can sand down the plastic spacers a bit to get eight speed spacing.
    I'm currently running one of these on an old rear wheel with eight speed STI pending an upgrade
    to a cassette.

    Haven't bent any axles so far - but at my age, I wouldn't expect to.....

    ^^^^^^
    That is *so* incredibly jarring to read for me.

    Nothing further to add here, carry on, don't mind me..

    Any competent LBS which services bicycles because they are current equipment on XMart full
    suspension bikes. If no LBS in your town, email me.

    Out here in reality, where a good percentage of 2003 bikes come standard with Chinese 8-speed
    freewheels, the SunRace is the common replacement, readily available at any competent shop which
    services bicycles. $29.95.

    SRAM discontiued all freewheel production three years ago.

    Yep. I have two of them.

    But no weaker in that sense than an 8 or 9-speed cassette wheel.

    Yep -- except that "bent" really means broken. Axles are much to hard to really bend. Look closer
    and you will see cracks. When I did this -- re-spaced my bike, re-dished my 30-year-old wheels and
    got the 8-speed freewheels, I broke about an axle a month in the summer. Quick-release, solid, name
    brand or no-name. All succummed to my mass.

    This begs the question of why? You can get a new hub for $30 or so, and a cassette to fit for about
    that much. Replace that old hub with a new one. Cassette hubs are inherently stronger.
