Product Story

Yes, this hub spins very smoothly due to extremely high tolerance machined bearing bores (.0002″, that’s 8 times thinner than the thickness of a human hair!) and high quality user-adjustable sealed cartridge bearings. The hub shell design has been refined over years of production and real world abuse to be as light as possible while still withstanding the abuse that the biggest, most reckless riders can put it through.

But the real star of the show might be the super-stiff, super-light, flex-free, interchangeable 7075 Alloy axle. Available in 3 configurations: Quick-Release, Bolt-On, and Thru-Axle, it passes from dropout to dropout (unlike the flexy, non-adjustable caps so common on cheaper hubs that love to pop off and roll under your car or workbench every time you take your wheel off). In the future, if you switch forks or get a new bike, you can easily change out the existing axle for whichever style of attachment fits your new fork.

Fresh bearings and axle conversion kits are available for hub overhauls and rebuilds in the Hub Service Parts section.

Made with pride in Chico, California.

Our monthly email is an ongoing bike conversation for creative people who spend a lot of time in their garage.
Y’all are weirdos. Well, some of you are weirdos Y’all are weirdos. Well, some of you are weirdos. Actually, most of you are weirdos. But some of you are really really weird and into bike bits machined from BRASS. (*cough* @monebikes *cough*). After we made some brass Baby Groovy barrel adjusters, we decided to make a batch of brass spring adjusters. These fit any and all of our rim brakes. Maybe this is a one-time thing (they weigh literally 3 times as much as our normal aluminum spring adjusters). Maybe we’ll offer them forever (they do look pretty cool). Either way, you’re weird for even reading this much about brake spring adjusters!
Here’s a little behind-the-scenes peek of our en Here’s a little behind-the-scenes peek of our engineers testing the Brompton Racer-M prototype brakes earlier this summer. We sold through the first batch of these in record time, but you can sign up to be notified when they’re back in stock on our website. But… why is Patrick so weird?
If you haven’t seen @hurrydive ‘s artwork…ye If you haven’t seen @hurrydive ‘s artwork…yes you have! He’s made some amazing posters for @lostandfoundbikeride and he made that epic MARS poster for @ultradynamico and a bunch of other killer art you may or may not have realized was him. He came up with this super cute and relatable froggie bike camping scene for us, so we’re doing a limited run of these BPA-Free Sustain (recycled) Nalgene bottles, live on the website now!
Look who’s back by popular demand! Apparently th Look who’s back by popular demand! Apparently the bike world is lacking in high quality reverse levers, so we dusted off the program and machined a few of these up. Yep, you can move the stainless pivot between short and long pull. Live on the website… NOW!
Awwww yeah, it’s time for Sierra Buttes Trail St Awwww yeah, it’s time for Sierra Buttes Trail Stewardship’s annual 5-Bucks-A-Foot fundraiser, and this year you could win a DIPPED @santacruzbicycles Heckler SL!

Head over to the @sierratrails website for a chance to win and learn about the absolute BEST trails in California! 🤯
We had A TON of requests for a PAUL brake that wo We had A TON of requests for a PAUL brake that would fit Brompton folding bikes, and after witnessing waaay too many bad and downright dangerous adaptations of our (and other crappy knock-off) brakes, we decided to do something about it. We modified the reach of our cult-classic Racer-M, and added a super stiff sealed-cartridge bearing roller bridge and adjustable trunion to make the most powerful, best modulating, most adjustable brake ever made for Brompton bikes. Yeah, Bromptons are weird, but we’re weird, and you’re weird, and sometimes it takes a bunch of bike-nerd weirdos to machine brakes this good, and that’s what we did! Full length video coming after we get back from @made.bike, but for now these brakes are available on our website.✌️
