    Freewheel Outer Gears

    Product Details

    When we designed our freewheels we intentionally made them rebuildable rather than disposable.  If you ride a lot, eventually you are going to need a new outer gear.  We recommend replacing your chain (and probably your chainring too) when replacing your outer gear because worn out chains don’t usually work well with new outer gears.

    Specs

    • Made from electroless nickel-plated 8620 case-hardened steel
    • Comes with an Enduro chromium steel bearing installed with snap ring
    • Bearings are are made from chromium steel, and use a special Mobil XHP222 extra high pressure grease
    • It’s a good idea to also purchase a new seal and O-ring when replacing your outer gear, available on the Parts>Freewheel Parts>Freewheel Seals page

    Compatibility

    • If you are switching your outer gear to a 16T freewheel or 16/19T double freewheel from any other size, you will also need to purchase a new lockring on the Parts>Freewheel Parts>Freewheel Lockrings page
      • 16T freewheel or 16/19T double freewheels us a slightly smaller lockring than all the other sizes
    • If you are switching your outer gear from a 16T freewheel or 16/19T double freewheel to any other size, you will also need to purchase a new lockring on the Parts>Freewheel Parts>Freewheel Lockrings page
      • 16T freewheel or 16/19T double freewheels us a slightly smaller lockring than all the other sizes
    • Compatible with 10 degree/36 points of engagement drivers/systems and 5 degree/72 points of engagement drivers/systems
    • 16T single freewheels work with 3/32″ chains only, not with 1/8″ chains
      • 16T gears do not have enough room at the base for 1/8″ chains to sit all the way down on the teeth
    • Double freewheels work with 3/32″ chains only, not with 1/8″ chains
      • 1/8 chains are too wide and may rub against the adjacent teeth
    • 17T-22T single freewheels will work with 3/32″ or 1/8″ chains

    Product Details

    Just a note that we don’t sell many freewheel bearings by themselves.  Usually if the bearing goes bad, your outer gear is probably worn out too.  The outer gears come with a bearing and snap ring installed so if you’re purchasing a new outer gear, you don’t need to purchase a separate bearing.  Our freewheel bearings are Enduro brand chromium steel and use a special Mobil XHP222 extra high pressure grease.
