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.

*SOLD OUT-Thanks for the orders!* Last weekend we *SOLD OUT-Thanks for the orders!* Last weekend we were tearing out the crawl space above the bathroom and found this giant box of old derailiures. We were going to try to recycle them as scrap but somebody said there might be interest in these weird old things so we put them up on the website for $25 each. There are about 250 of them, so if nobody wants them, we’ll probably try to figure out a way to recycle them. ♻️🚮
We’re SUPER excited about this new trail network o We’re SUPER excited about this new trail network opening just up the mountain from us above Butte Meadows! Two trails are already finished, with 5 or 6 more in the works, and an eventual plan to connect this to the @sierratrails Connected Communities trails. Yeah, this is big! So… we asked @the.scorps if he’d be willing to donate artwork for a fundraiser T-Shirt, and he doodled up this fun drawing of the Colby Mountain Lookout. These are VERY limited edition, so if you want a sweet rare McNally shirt while raising money for a killer trail system in Lassen National Forest, head to our website quick before they’re gone! 📷: @explorebuttecountyca
It’s no secret our water bottles are made in the U It’s no secret our water bottles are made in the USA by @specialized_custom and it’s also no secret we’re passionate about recycling around here. Well, they just started offering a couple new bottles made entirely from 100% recycled material. While we aren’t crazy about putting more plastic out in the world, it may as well be 100% recycled AND recyclable, so we’re offering this option in our Dune Buggy bottle, in this Teal color. Soooo…. Did this thirst trap of @jxrad trick you into reading this far? ♻️
Happy Friday! Paul designed our first seatpost (th Happy Friday! Paul designed our first seatpost (the “Tall & Handsome”) with 26mm of setback to accommodate Brooks saddles, and while it’s become a cult classic, we’ve had requests for years now for something of the same high quality in a zero offset. We took the extra design time to dial in every feature WE want to see in a simple, reliable, beautiful seatpost, then machined it to our super high tolerances right here in Chico California. Head over to our website and get to know this elegant new family member, it’s in stock and shipping now!
