Paul Components machine these hubs from three inch round bars of 6061 aluminum. The hub shells are put through four different machining processes before they go to finishing, and the end result is something to be proud of. The wide flanges have six window cutouts in them to save weight and draw on the influence of classic track hubs.
The hub shells are available with dedicated fixed gear threading on one side only, or in a flip-flop version with fixed threading on one side and freewheel threading on the other. Proper left-handed lock ring threading keeps fixed gear cogs secure, and heavy-duty stainless steel lock ring is included.
The axle is ground from 7075 aluminum, which has a great strength to weight ratio. The outer lock nut faces are made of knurled steel for a solid grip against dropouts. Hubs are available with 120mm outer lock nut spacing. The ends of the axle are threaded to receive stainless steel axle bolts. Hub service parts are available to convert between axle lengths.
Paul Components High Flange hubs use high-fill sealed bearings and they can be adjusted with simple adjuster ring.
The chainline on the High Flange Rear is spaced to 44mm for the fixed cog, and 48mm for the freewheel.
Spoke hole counts are available in 32, and the spoke holes are chamfered to reduce stress on the head and elbow of the spoke.
