Titanium 29er Custom Built Profile

This lightweight, made to measure 29er I designed for a Canadian customer is used for 24 hour racing and epic riding in the mountains of Alberta. I needed to get as much standover clearance as possible for his relatively short inseam. This is where 29ers meet their design limits due to their tall crown height requirements. I stretched the limits by radically sloping the top tube and then bracing the seat tube with a 1" tube. The head/tube was designed short to provide every bit of stand over possible . The t/t is mitre'd into the d/t to squeeze it all in there. The seat tube is left about 19" long so that the seat post doesn't stick out a mile and the seat stays intersect nicely with the s/t brace. The owner named it "Airtight alibi" - his frame turned out light, laterally rigid and aesthetically unique.

Jason at El Camino fab flawlessly executed the CAD design by providing the miter operations and tig welding on the frame. He also added some custom bends turning non descript 7/8" 3/2.5 ti tubing into beautiful s - bend stays. This frame received all the good stuff. U.S. Made 3/2.5 ti tubeset. 6/4 ti Paragon "Wright Bros" hooded dropouts and Paragon cable stops, etc.



After getting the frame back from El Camino I did the satin polish with scotch brite pads, laid down some custom cut decals and then applied a final sealant/polish.





All of the frames ti surfaces were prepped with anti-seize and then I built it into a complete. The list of parts on this 2-9 x-c flyer would please any rider.
