The modular pulley design allows you to mix and match pulley sizes and hub adapters. In seconds you can go from 32t to 36t (or 40, 44t). You can also then use the pulleys on different hub adapters. All parts are made from aircraft grade 7075 aluminum and anodized black.
The Flyhweel Hub Works with:
83, 90, 97, and 107mm Genuine Flywheels
83, 90, and 97mm Clone Flywheels
100mm MBS Wheels
The Kegel Hub Works with:
80mm Orangatang Kegel (Orange and Purple)
85mm Orangatang Caguma
90mm and 100mm Boa Wheels (All Colors)
The modular hubs uses an 11mm bearing that is shared between the wheel and hub adapter. This allows modular pulleys to be used, (any size: 32, 36, 40, 44t). They can be found here individually or if you want a hub adapter + pulley you can find that here
What trucks will these work with?
Standard Caliber 2 Trucks: it is necessary to flip the outer lock-nut and use only one inner speed ring between the pulley bearing and truck axle
Paris Trucks: same procedure as Caliber
TorqueBoards 218mm Trucks: fits perfect without and different procedures
Any other truck with 8mm axle and less than 28mm hanger width
Let’s say I use my current bearings instead of the provided 11mm bearing, will there be an issue with the pulley coming off the wheel or it not being concentric etc?
