VeloFuze Boost Hub Adapter 12mm x 142mm to 12mm x 148mm Boost spacing ~ Boost Hub Conversion

Boost is a waste of time and $$ in my mind, buy this kit and run a normal set of wheels and cranks in a boost frame like I did in a Salsa Deadwood.

Good quality bit of kit. Takes a little more care when installing wheel but saves buying a new wheel/hub. Would buy again

Cheap and work, just easy to lost the space

does the job- does not require you to re-dish your wheel... if you've got a 148 bike with extra 142 wheels, this is the ticket... when you adjust your rear derailleur make sure you leave enough slack in the cable so that if you swap between a 142 and 148 wheel all you have to do is turn the barrel adjuster to slacken the cable and reset the limit screws...
