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

Fixed Word

We saw a need for high quality 135mm Bolt-On and 142mm Thru-Axle fixed gear hubs, and with our long history and experience making single speed and fixed gear hubs, we knew how to do it right. These beauties are machined 100 percent in-house by us here in Chico, California. They’re absolutely bomb-proof, very light, easily adjustable, serviceable, and come with our own extra thick stainless steel lockring.

$153.00 – $159.00

Product Story

We machine these hubs from 2-1/8″ round bars of aircraft grade 6061 American made 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 flanges are canted towards the rim, and the spoke holes are chamfered to reduce stress on the head and elbow of the spoke.

The hub shell is available with dedicated fixed gear and lockring threading on one side, with or without a set of standard freewheel threads on the other side. Proper left-handed lockring threading keeps fixed gear cogs secure, and our heavy-duty stainless steel lockring is included.

The interchangeable axle goes all through way through the hub and is precision turned in-house from 7075 aluminum, which has a great strength to weight ratio, and is available in 135mm Bolt-On or 142mm Thru-Axle. No flexy, easy-to-lose caps here!

We use high-fill replaceable sealed bearings, and they can be easily adjusted with our simple adjuster ring.

If you’ve ever taken a tour of our facility, you’ve seen the rows of custom bikes hanging in the rafters in the machine shop. He’s built a few @surlybikes Krampuses over the years and is a big fan, so he built this one up just for #InternationalSingleSpeedDay . It’s a simple no-nonsense build with a lot of our (and @whiteind ) parts, and that deep metallic plum paint is pretty dang nice!
Happy #InternationalSinglespeedDay everybody! Head Happy #InternationalSinglespeedDay everybody!

Whew, thanks everybody for your patience! Running Whew, thanks everybody for your patience! Running a machine shop with Covid-safe zones and staggered shifts is NOT fun or easy, but we’re still cranking out the bike parts. I.S. and Flat Mount Klampers are back up on the website today, and we REALLY appreciate everybody’s patience while we’ve been catching back up!
Holy smokes, @the.scorps made us some new graphics Holy smokes, @the.scorps made us some new graphics for our event vans and we installed the first set today and DANG he nailed it! (Scroll through!👉) There are sooo many little Easter eggs hidden throughout the panels and he captured our culture and what makes us tick PERFECTLY. There’s too many details to post here, so next time you’re at an event we’re at (yes, this WILL happen one day) stop and let your eyesballs take a little journey around this artwork. Thanks Chris!!
