Zipp Speed Weaponry Conversion Kits

  • ⋅ Only to be used to convert Zipp's 188 V7 10-speed rear hubs to 11-speed
  • ⋅ Not to be used on 188 V6 or earlier rear hubs


 In October 2012 a new rear hub version was released to accommodate Shimano11 and Campagnolo 11 speed drive chains. The 188 V7 (2012 gray and black) rear hub was modified as follows:

  • Overall drop to drop length (OLD) is increased by 0.8mm
  • Axle internal diameter is reduced by 1.0mm (walls are thickened to increase axle strength) (left in image)
  • Non-drive side rear end cap is reduced by 1mm, 'O' ring removed and colored black (left in image)
  • New 11 speed free hub with laser etching, serial number and shim for 10 speed

The V8 88/188 hubs are only available in black, they build a rear wheel which is more durable and marginally stiffer at the same spoke tension. The axle, end cap and free hub are not compatible with the older hub versions (2009-2012). A conversion service is available for only for 2012 188 hubs (gray or black).
