High Flange Rear – Paul Component Engineering Skip to content

Covid-19 Update:

We’re still receiving and shipping orders, and really appreciate your support! Please be patient, as it may take a few weeks for orders to be shipped under the current manufacturing circumstances. Rest assured, we will get your parts to you as fast as we are able to, while still observing Covid-19 safety protocols - even if you don't hear from us.

International Customers: We have been seeing parcels sit in customs all over the world for up to 2 weeks with no update to the tracking information. These orders are eventually delivered, you will just have to be extra patient.

Thank you,

The PAUL Crew

Product Story

We 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 we’re very 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 our 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. Two axles are available with 120mm or 130mm outer lock nut spacing. The ends of the axle are threaded to receive our stainless steel axle bolts. Hub Service Parts are available to convert between axle lengths.

We use high-fill sealed bearings in the High Flange Rear, and they can be adjusted with our 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 24, 28, 32, and 36, and the spoke holes are chamfered to reduce stress on the head and elbow of the spoke.

We’re super lucky to have a network of great bik We’re super lucky to have a network of great bike paths in Chico, one of which follows an old railroad route and leads right to the back gate of our shop! Bike commuting is awesome, and we figured it was time for us to pitch in, so we adopted a little stretch of path, and we go and pick up all the trash every couple months. 🚮 Ding your bell if you see us out there! 🛎
We got a package in the mail from @alternativebike We got a package in the mail from @alternativebikeco the other day with these blasts from our past in the box. Back when Moon Units were smaller and had a more finicky pinch bolt, back when people bought brake lever extensions so you could use your brakes from your bar-ends, and back when instructions were rudimentary drawings and said things like: “Hey- Be cool to the ground.” Thanks for the trip down memory lane!

Good feelings all around! Now then…what kind of bike should we build @sierranevada next year?…🤔
