Product Story

Machined in Chico California to the highest tolerances. It takes a LOT of miles to wear these out, so if you need to replace yours, we’re impressed!

*These pulleys are not compatible with our previous generation Melvins that used plastic pulleys.

Our monthly email is an ongoing bike conversation for creative people who spend a lot of time in their garage.
We get a LOT of weird emails around here. A good p We get a LOT of weird emails around here. A good portion of them are normal tech questions like: “Hey Paul, what size this part do I need to fit on that bike?” And quite a few: “You should make this super obscure bike part that I’m the only person in the world who will ever want one.” 😂 And then every once in a while we get an email out of the blue, like this one, that just said: “I have completed the Paul’s Canti Road test. My brakes have taken me to every state in the USA via bike from CT. Test Results: PASSED A+” What a gangster, thanks for bringing us along Kenneth!!
The new Ride To Work Challenge sheets just dropped The new Ride To Work Challenge sheets just dropped, here’s your chance to win a burrito and a beer from your coworkers by riding to work when they wimped out because “it was too cooold!” (said in mocking wimpy whiney voice)(…this is easy for us to say living in California though😂).

Do you want to win a free Surly Krampus decked out Do you want to win a free Surly Krampus decked out in PAUL parts, OR WHUT?! All they make you do is go to thier website and sign up for the newsletter, it takes about 30 seconds. Look at all the zits on this bike, you can bolt everything you own to this puppy, ride out into the woods, and ABANDON CIVILIZATION! Ok, that’s drastic, you could also just put a shock on it and go shred some nice trail and make it home for dinner. Tell @surlybikes what you would do with this bike in the comments and maybe it will convince them to cheat on your behalf. 🎲🎲 Nah they wouldn’t do that, would they? You have untill Friday to enter!
Oh dang, Saturday is #InternationalSingleSpeedDay Oh dang, Saturday is #InternationalSingleSpeedDay already! Y’all know the rules already, there are no rules. Get out and ride a singlespeed alone or with friends or with dogs or your pet rat or throw a local group ride like @pdxcoffeeoutside. Ride your fancy singlespeed or your mom’s beachcruiser or take the battery off your silly electronic shifting bike or ziptie your shifter so you can’t shift or ziptie your fingers together so you can’t shift?!

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!

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?
