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.

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.

Instagram post 2191609022691896846_25667512 We already had quite a few requests for our Set N’ Forget Thru-Axle Skewer in a size to fit the latest @columbus_official forks, so when @allcitycycles started to spec these forks on bikes like their Nature Boy, Cosmic Stallion, and Macho King, we decided we’d better get on it. So yeah, 12x132x1.5 in stock on our webstore or from your favorite bike shop...NOW!
Instagram post 2191051020112772962_25667512 We’ve been supporting Grinduro since its humble beginnings with our aid station up on Mt Hough, sometimes even twice during the same event. When Sierra Buttes Trail Stewardship asked us if we’d still like to be involved as the event transitions into Mountain To Meadows in 2020 we said HELL YEAH! In the last 10 years SBTS has secured more than a million dollars worth of grants, donations, and revenue from events like these, which it invests right back into into the incredible trail networks and local communities in and around these small mountain towns of the #LostSierra. They also know how to throw a party, and with a new improved course, a new cross race, AND Meet Your Maker wrapped in, this is going to be one hell of a weekend! Head over to the link in @sierratrails bio, sign up for the registration notification and we’ll see you there! 📷: @theradavist (always with the BEST coverage👀)
Instagram post 2190349999443264499_25667512 Last year we collaborated with All Hail The Black Market to machine these ultra high tolerance AHTBM lazered 45 adapters and it looks like he’s down to the last 11 of them! Maybe a good Christmas present for your bike-nerd/record-collector buddy? Only $12 on the @allhailtheblackmarket website, link in their bio.
Instagram post 2190185763374976277_25667512 There’s a reason these Flex Fleece Hoodies have a cult following...they’re super soft, warm, and cozy on the inside, super durable, Made In the USA, and that @loomsville Barbarian artwork is EPIC!
Instagram post 2186674045743056444_25667512 Okay maybe we went a LITTLE overboard here. But hey, you only turn 30 once! 🎉 Every step of the way on this project we would come up with something else special to do and were like “YEAH LET’S DO THAT TOO!” 😂 Each one of these Limited Edition 30th Anniversary Box Sets started in Paul’s woodshop in his yard, with him personally milling the planks square and corner rounding the edges. 📐 Then he brought them to the machine shop to be CNC engraved with the PAUL logo, individually numbered (1/30-30/30), and get the pockets cut out. Then they went BACK to Paul’s woodshop where he sanded and finished them all before bringing them BACK to headquarters to install the brass hinges and clasps. Meanwhile, we anodized a small batch of Klampers, Canti Levers, Seat Collars, and Bottle Openers in a sweet alternating Smoky-Pewter/Royal-Purple colorway, and engraved each part with the number “30”. The finished box set is STUNNING. 🤯 The question is...will you be able to resist taking these out of the box, putting them on your, bike and getting them dirty? We put all 30 of these on our website today, go take a look to learn more!
