Hub Replacement Parts Information

Direct replacement parts for Shimano and non-Shimano hubs. If you know the model name or model number of your Shimano hub, you can find the parts you need on our Shimano Hub Parts Page. If you are unsure of the parts you need, or need a better understanding of how to identify replacement parts, please refer to the technical information below:


  • Diameters:
    • Measured over the threads. Currently available in 9mm, 9.5mm (3/8") and 10mm diameters
  • Thread Pitch:
    • TPI - Threads Per Inch (Typical for Campagnolo, Taiwanese and BMX hubs)
    • 1mm - Millimeters per thread. (Typical for Shimano hubs)
  • Length:
    • Hollow axles, for quick release skewers, are usually 11 mm longer than the hub/frame spacing, so that 5.5 mm of axle sticks out past the ends of the locknuts.
    • Solid axles, also known as Nutted or Bolt-On, are typically 45-55mm longer than the hub/frame spacing. The axle may extend beyond the outside axle nuts.
      • Road Frame Spacing (rear):
        • 120mm: 5 speed
        • 126mm: 6,7 speed
        • 130mm: 8,9,10,11 speed
      • MTB Frame Spacing (rear):
        • 130mm: 7 speed
        • 135mm: 8,9,10 speed
      • Track Frame Spacing (rear):
        • 120mm
      • Front Fork Spacing:
        • 100mm
      • Tandem Frame Spacing (rear):
        • 140mm
        • 145mm
        • 160mm

Our axles will note the overall length, thread pitch and whether they are solid or hollow.

Cone Dimensions


Cones are a bit more difficult to find the proper replacement if you do not know your hub model.

  • Measure the diameter and the length of the cone. We list complete dimensional data for each Wheels Mfg cone.
  • Axle diameter/pitch. Need to measure with a known axle. If it threads on, it fits!
  • Seals or no seals? Cones that have a dust/grease seal will have a groove in it. If our Wheels Mfg cone does not come with a seal, remove and re-use the seal from your existing cone.
  • Please note that most rear hubs use different cones for the right (drive side) and the left (non-drive side). All Wheels Mfg rear cones are designated right or left.
  • Visually match your cone against our cones.
  • Wheels Manufacturing cones are precision machined to Shimano Ultegra or higher quality standards. This ensures that our cones fit correctly, run smoothly and have a long service life.

    • Shimano rear cones fit 10mm diameter axles
    • Shimano front cones fit 9mm diameter axles
    • Taiwanese cones fit 9mm, 9.5mm, and 10mm diameter axles
    • Note: there are some exceptions – use your old cones for reference.

    If you cannot find an exact fit cone from our hub/cone charts, you will need to measure your existing cone and axle to find an approximate fit. Measure your axle thread size, the cones outer diameter and overall length. Undersized cones can be used if you find a cone close to your original. You can also add axle spacers to take up any spacing issues if you are forced to use a narrower cone.

Wheels Mfg sells sealed cartridge bearings, ball bearings in complete bearing retainers or loose ball bearings.

  • Lose Ball Bearings - measure the diameter of one of the balls, count the total number used for each side.
  • Retainer Bearings - remove a ball from the retainer. Measure the diameter of a ball. Count the number of balls in each retainer.
  • Sealed Cartridge Bearings - Locate the bearing number on the rubber seal of the bearing. It will be something like 6801. Often times this number is hard to read. Measure the outside and inside diameters and the width.

All axle spacers are machined aluminum and have a 10.1mm inner diameter.

  • Stack spacers together to get the width you need. If your hub calls for an 8mm spacer, use a 3mm and a 5mm spacer.
