    Shimano MF-7400 Freewheel? Is this Uniglide? Please Help!

    I have an older Tommaso race bike with a 7-speed uniglide freewheel that is worn out and needs replacing. After searching online, the cheapest 7-speed uniglide I have found with the gearing I want is out of my price range for now. HOWEVER, I have found the mf-7400 for half the price. The problem is, I can't find any listing for its sale that says it is designed for a uniglide hub.
    Sheldon Brown states that all Dura-ace freewheels in the 6/7 speed variety are uniglide, and I found this site http://www.bikepro.com/products/freewheels/shimfw.html that seems to say the MF-7400 will work on a uniglide hub.
    I'd just like to get conformation that this will indeed be compatible on my bike before I throw down the dough.

    Any help is much appreciated!

    It sounds like you are looking for a 7-speed Uniglide cassette, not freewheel. In that case, the MF-7400 freewheel will not work.

    It is a uniglide. Looks like I'm stuck springing for the more expensive cassette.
    Thanks for the help.

    A nice MF-7400 can fetch close to $40. I sure hope you're not spending twice that for a cassette!

    The only uniglide cassettes I have found have been in the $90-110 range. What's worse, all I have found with the gearing I want are dura-ace, and I have recently learned that the dura-ace uniglide cassettes only work with the dura-ace hub (mine are 600's).
    I did find a place that has converted hypoglide cogs into a uniglide cassette, those are *only* $65 after shipping.

    I think I am just going to try to squeeze as much life as I can out of mine. Flip the cogs around, and try to clean/soak/replace the bearings on the freehub body.

    If you have a 74XX series hub why not swap out the freehub body? You can only use a DA body, they're expensive but you'll be able to use any cassette you'd like from 7s-10s.

    If it's still having troubles performing after I do a bit of a overhaul on it, I will likely do as you suggest.
    I just hate spending money
