The benefits of the Boost format (15x110 mm and 12x148 mm) are well established. Better clearance for tyres and larger rims and reduced dish for stiffer, stronger wheels. The major downside? To take full advantage, you need not only a new frame and fork, but also new wheels.

In response, we developed the Boostinator. When paired with compatible 15x100 mm or 12x142 mm hubs, Boostinator kits allow existing wheels to be mounted in standard Boost frames and forks. Disc and drivetrain positions are maintained and, thanks to quick reframing, spoke bracing angles are improved.

Boostinator kits consist of a specially designed axle end cap and, in the case of rear kits, a precision machined rotor spacer with a set of six high-strength bolts. In accordance with Boost specifications, the disc and cassette are offset outwards, allowing brakes and derailleurs to function as intended.

Compatibility

• Specific model compatibility listed below in the "Models" section
• Front boosters are just an end cap and do not require a rotor spacer. The wheel is re-dished
  
• Rear boosters require both a flat and a rotor spacer 
• Rear Boostinator kits are not approved for rotors over 183 mm
  
• Hub spacing is 100 mm at the front and 142 at the rear, and the Boostinators make them 110 and 148 respectively
  
• Compatible with 6-bolt FRONT wheels and certain centre-lock models
  
• Compatible ONLY with 6-bolt REAR wheels (there is no way to space centre-lock rotors more than 6 mm) 
  
• NOT recommended (or safe) for asymmetric lacing such as 2:1 lacing found on some Industry Nine wheels

Technical specifications
