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’d like to take a minute to sincerely thank ev We’d like to take a minute to sincerely thank everybody who’s been so patient while we machine and build bike parts and ship out orders as fast as we possibly can while keeping our work-family safe and healthy. Making everything in-house means it can be a real challenge when it comes to dividing up all of our production areas into Covid-safe zones, and working staggered shifts (even on the weekends) has made 2020 a real challenge for us. Yesterday we were able to put some more brakes and brake levers back in stock on the website and we just replaced one of our CNCs with a fancy new (faster) machine, so we’re feeling optimistic. (The recent news of two vaccines makes it seem like there might be a light at the end of this tunnel?) Anybody want to see some setup videos of our new machine or does that just make your eyes glaze over?
