http://www.lynskeyperformance.com is located in Chattanooga Tennessee. We build a Titanium race bicycle to go very FAST. Many of you have anticipated the incorporation of the Helix downtube into the new 2010 Procross Cyclocross frame. We are happy to introduce it to you as we walk thru the drawing, fine tuning in the weld jig, welding and finally a brief walk around by David Lynskey, the developer of the Helix technology. Contact us anytime to order, to ask questions, or just to talk titanium bikes!! 423.499.5815
