    Shimano Alivio Crankset

    I have a 1997 GT that I am working on and it has a Shimano Alivio FC-MC16 crankset as seen here:
    http://bernd.sluka.de/Fahrrad/Shiman...-MC16_1997.gif
    The chainrings will unbolt but they are a riveted set and appears that it must be replaced as a unit. I have found another site stating that the PCD is 67mm yet I cannot find a chainring listed in this size. I am trying to learn and understand. My assumption is that I am just out of luck and the drivetrain needs to be replaced. I would like to keep this assembly if I can. Any thoughts?
    Thanks!!

    Unless for some reason you want totay 100% original, you could get a whole new equivalent quality crankset cheaper than replacing rings.

    The Alivio and several similar Shimano crankset models came on rather low line bikes and weren't expected to be used enough to wear them out. They were heavy and inexpensive and any set of half-decent chainrings would cost way more than the entire Alivio brand new.

    If you have worn out the rings or want different gearing, I'm afraid you will have to replace the entire crank and, probably, the bottom bracket too. Nashbar has a couple of house-branded double and triple cranks and matching ISIS bottom brackets that are very attractively priced. They would be your best bet for a replacement/upgrade at minimal cost.

    If I were you I'd be looking at a FC-M510 Deore or FC-M572 LX hollowtechs cranks. The LX FC-M572 crank can be found on ebay for $75.00 right now and I've seen the FC-M752 XT crank going for $89 dollars at Jenson or Cambria. There was a FC-M510 Deore that went for $35 range last week on ebay, $59 at the bikesmart link below. Better yet $44.95 at Cambria. All of these cranks would have alloy chain rings and be lighter weight.
