The Syntace X-12 System

We are ringing in the New Year with a new dropout that is compatible with the Syntace X-12 System.  This system provides a unique solution to the wheel centering problems that arise from the fixed positioning of a through axle.  Making use of concentric or eccentric threaded inserts in the right side frame component, the wheel can be centered in the frame following any inconsistencies that arise during frame construction.

Paragon Machine Works machines the steel and titanium (coming soon) frame components and a Shimano Direct Mount hanger (coming soon), with the remainder of the parts manufactured by Syntace or DT Swiss.  We will stock all the parts listed below, allowing for the purchase of a complete assembly.

Giving Back:  Friends of Tamarancho

Paragon Machine Works donates 100% of all revenues from the sale of our bottle openers and promotional items to non-profit organizations that promote bicycle safety, awareness, and community.  During the month of December we raised over $1300 for Bike East Bay to help them build community support and advocate with city staff to bring their Tunnel Road project to completion..

In January we will donate all revenues to an organization that is near and dear to our hearts and homes, the Friends of Tamarancho.  The Marin Council, Boy Scouts of America operates Camp Tamarancho, which is located 45 miles north of San Francisco in the hills above Fairfax, CA.  Camp Tamarancho’s 480 acres includes campsites, cabins, and mountain biking/hiking trails nestled among gorgeous meadows, rolling hills, and redwood and oak forests.  The excellent mountain biking trails on the camp property are designed and maintained in partnership with the Friends of Tamarancho.  This is the only park in the area where bicyclists are REQUIRED to stay on the swoopy, sometimes technical single track; many of our staff can attest to the challenge, beauty, and thrill of riding in Camp Tamarancho.  For more information visit their Facebook pages, Friends of Tamarancho and Camp Tamarancho Flow Trail.  You can purchase your 2015 annual access pass here.

We appreciate your support!

Total amount donated to date:  $4596
