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.

When it came to handlebars for the #SierraExplorer When it came to handlebars for the #SierraExplorerBike , Paul wanted to run the @jonesbikes H-Bar, so we dialed up Jeff Jones himself. Not only was Jeff stoked on the project, he also wanted to show us his exact method for wrapping the bars and which grips he likes and where to position the shifters and brake levers. So we sent him our Microshift Thumbie and some shiny Polished Canti Levers, and he made this nice little video of proper H-Bar setup. (We MIGHT have added a little music to it😉). Thanks Jeff, this is gonna be a very cozy setup for whoever wins the finished bike! Speaking of which, obviously @sierranevada won’t be displaying and giving away this bike as early as we had planned, what with this stinky Covid-19 🦠 making parties so dangerous. So for now, we’ll continue enticing you with these little process videos and photos until we are in a place to lay out an alternate plan, and we WILL be giving this bike to one of you weirdos and we expect you to TAKE IT BIKEPACKING! (When it’s safe to.) Stay tuned... 📺 🍿
Here’s where our Klamper Disc Brakes get their ⚡️POWER⚡️. Oversized bearings ride in the CNC machined races of our heat-treated steel pistons. 🦾 We also use roller-bearings instead of plastic thrust washers because this brake is designed to last a lifetime with minimal service. Available in almost every configuration possible, from Flat-Mount to Post-Mount, Short-Pull, Long-Pull, and even Campy-Pull! ⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀ *We are still currently accepting and shipping orders, see our last post for details. ✌️
Time for a PAUL Component update! Yes, we’re loo Time for a PAUL Component update! Yes, we’re looking into ways we can adapt our machine shop for production of medical supplies (like ventilator components), but in the meantime the machines are shut down. Luckily we have a very healthy stockpile of components on the shelves and a safe method for shipping them. We’re still receiving your orders, and really appreciate your support, but please be patient as it may take a day or two longer for us to get your orders out under the current circumstances. Ordering through our website is the easiest and most efficient method to reach us and we’ll be extending the 10% discount to help take the edge off, just use coupon code “ridesafely” at checkout. This works for shop orders through our B2B as well! Our top priority right now is the safety of our employees and the community at large. So far there have been two reported cases of Covid-19 in Butte County and now is the time to follow CDC guidelines and flatten the curve. We’ll continue doing our best to provide you with the bike nerd content you love, and already have some fun ideas for some social distancing videos. Riding bikes is what helps us stay sane through times like these, and now’s a great time to enjoy the outdoors if you can do so safely. Stay in touch, we’ll get though this together! ✌️ 📷: @renaissance.cyclist
From bars of American alloy to polished hubshells From bars of American alloy to polished hubshells ready for their axles, we’re serious about the details every step of the way. Our parts are designed and machined to be a long term investment in durability and serviceability. And, well...we think they look pretty nice too...😍.
Any of you ever heard of Air Art? Russ Pickett is Any of you ever heard of Air Art? Russ Pickett is a LEGEND of bicycle painting! He painted all those sick Mountain Goat bikes back in the day, Retrotec, numerous National Champion frames, etc etc. He’s “officially retired” these days...BUT...somehow Tyler of @btchn.bikes talked him into painting the #SierraExplorerBike for us! This is a super complicated (pain is the ass) job of taping down topographic map 🗺 lines one at a time, then a subtle green fade front to back. Stay tuned for more updates on this bike we’re building for @sierranevada , there will be a text-to-win and it could be yours!
