Chain Keeper – Paul Component Engineering Skip to content

Covid-19 Update: We still 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 order confirmation sent, and orders shipped under the current circumstances. Rest assured we will get your parts to you as fast as we are able to while observing safety protocols!

Chain Keeper

The Chain Keeper is a guide to keep your chain right where it belongs. Mounted in place of a front derailleur, the Chain Keeper works with single chain ring drivetrains using a narrow chain. The chain block surrounds the chain as it meets the chain ring and prevents it from skipping off.

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...😍.
