Burls titanium fixed

*3. How do Burls titanium bicycle frames compare in weight to Burls steel bicycle frames?

                Burls steel bicycle frames can be surprisingly light, especially                      when built with high end tube sets, but to put it in perspective                      if we take a medium sized steel frame, say a 55cm c-c top                      tube built from Columbus Spirit, the top end tubeset in the                      Columbus range with a min wall thickness 0.38mm, its weight                      will be approximately 1600grams. A similar sized Burls titanium                      frame built from plain gauge 3/2.5 with a wall thickness of                      0.9 mm will weigh in at around 1370 grams.

*about 230g then (so the weight of a mid range seatpost)

edit: he fillet brazes his columbus spirit frames so a bit less if it's tigged
