Covid-19 Update:

We’re still receiving and shipping orders, and really appreciate your support! Please be patient, as it may take a few weeks for orders to be shipped under the current manufacturing circumstances. Rest assured, we will get your parts to you as fast as we are able to, while still observing Covid-19 safety protocols - even if you don't hear from us.

International Customers: We have been seeing parcels sit in customs all over the world for up to 2 weeks with no update to the tracking information. These orders are eventually delivered, you will just have to be extra patient.

To learn more about what it's like to be a machine shop during a pandemic, watch this cool video we made!

Thank you,

The PAUL Crew

Product Story

IS mounts are the type with the mounting screws that install horizontally. We make them in +0, +20 and +40. Plus zero are for 160 front and 140 rear rotor sizes. To go bigger just add 20 0r 40mm. So a 180 front rotor will need a +20 and a 200 or 203 will need a +40. (160 plus 40 does not equal 203, but that’s ok).

The post mount version works the same except the caliper mounts to frame or fork directly through the caliper holes. For 160 front  and 140 rear, no adapters are needed. For bigger rotors, you will need the adapters.

We adopted a bikepath with help from @chicovelobik We adopted a bikepath with help from @chicovelobike ! This is a route we use every day for commuting to work (it passes right behind our shop), so it felt really good to get it all cleaned up today. Bikes are more than recreation, they are also transportation! #ChicoVelo #AdoptAPath

A Shimano Thumbie coming fresh out of the CNC. It’s about to get hand deburred, tolerance and threads checked, visual inspection, and then taken into the tumbling room for a nice satin surface finish before anodizing. All this fussing just to put a particular shifter in a particular place? Some people like the feel and placement of thumbshifters, and it’s a great way to convert drop-bar/bar-end bikes to riser/flat/mustache-bar bikes. We also make these in SRAM and Microshift compatible versions. ✌️
