Wheels Manufacturing produces 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 details 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:

Hub Axle Help Chart


Wheels Manufacturing axles will note the overall length, thread pitch, and Wheels Manufacturing will note overall length, diameter, thread pitch and call out the axle as a solid axle or a hollow axle.

  • 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:
    • 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
    • Hollow axles: 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.

Cones CN-R096 Cone - Bicycle Parts Direct

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

  1. Measure the diameter and the length of the cone. All Wheels Mfg cones list these dimensions.
  2. Axle diameter/pitch. Need to measure with a known axle. If it threads on, it fits!
  3. Seals or no seals? Cones that have a dust/grease seal will have a groove in them. If our Wheels Mfg cone does not come with a seal, please remove the seal from your existing cone.
  4. 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.

Bearings Ball Bearing Retainer 3/16 x 7 - Bicycle Parts Direct

  • 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 the ball. Count the number of balls in each retainer.
  • Sealed Bearings – Measure your current bearings ID, OD, and depth.


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.
