Kit designed to convert the Boost rear Shogun, and Boost Tairin S1/R1  hubs to Superboost spacing.
 
Converts from:
Rear (12x148mm) to Rear SuperBoost (12x157mm) with a strong, symmetrical, and centered wheel spacing
 
Rear kit:
Consists of a left side end cap and a snap-on brake spacer adapter.
Brake adapter snaps onto rotor mount surface of hubshell, so there is no torquing and flex when braking. With 6 recessed holes for standard bolt-to-hub, and another 6 holes for standard bolt-to-rotor; this means that there is no need for propietary long rotor bolts. Left side end cap adds 9mm of axle length, the hub is offset 4.5mm towards the right, improving bracing angles, and effectively benefiting of the extra axle spacing, by converting the hub to a symmetrical non-dished wheel, spaced at 157mm (compatible with any 12x157mm frames). If conversion is made on a built wheel, wheel dish has to be moved 4.5mm to the left.
