Part of that is building a bike you will love and want to keep, and part of that is making it durable by using top quality materials and careful workmanship. Both my chosen frame materials (titanium and steel) are recyclable if needed.” –John Caletti

“At the heart of a bicycle is the frame. It is the soul of the machine. It is one of the most expensive parts and the part that will give your ride its character, its feel and its purpose.”
At Condor the frameset is extremely important to us; it has and always will be. That is why after sixty-five years we still make all our frames by hand to our specifications in our production facility. If we go back to when Condor started we used the most famous tubeset in the world; Reynolds 531.”
“In 1948 the majority of race bikes were bespoke but in today’s marketplace, a bespoke bicycle is a rarity. At Condor, it is what we have done every day for sixty years.”

Built with Columbus XCr: unlike other stainless steel tubesets, Columbus uses seamless stainless steel, which enables the tube walls to be drawn extremely thin at just 0.4mm. This keeps the weight low whilst having a higher stiffness to weight ratio than Titanium. It is corrosion resistant, too.
