Boost Adaptive Kits (135/142 to 148)

Kit designed to convert the standard front and rear Shogun, Zen, and Tairin S1/R1 hubs to boost spacing.
 
Converts from:
Front (9x100-12x100-15x100mm) to Front Boost (15x110mm)
Rear (10x135-12x142mm) to Rear Boost (12x148mm)
 
Front kit:
Consists of an end cap that replaces non-disc side of the hub, effectively adding 10mm of axle length, the hub is offset 5mm towards the left, improving bracing angles and effectively making spoke lengths and angles symmetrical. If conversion is made on a built wheel, wheel dish has to be moved 5mm to the right.
 
Rear kit:
Consists of a left side end cap,  proprietary snap-on brake spacer adapter, and longer rotor bolts of grade 10.9. Brake adapter snaps onto rotor mount surface of hubshell, so there is no torque and flex when braking. Left side end cap adds 6mm of axle length, the hub is offset 3mm towards the right, improving bracing angles, and effectively benefiting of the extra axle spacing. If conversion is made on a built wheel, wheel dish has to be moved 3mm to the left.
