I have only built a few like this but I am anxious to get it painted and to the customer to hear the ride report.
The front triangle is all True Temper OX with a 38 mm downtube , 35 mm seat and top tube.
The rear triangle is all columbus -I think it is called 'Life' but I'm not 100% sure.......it is the best stuff I had. I did a little re-work on te seatstay bends to get the stays close enough for a brake bridge to fit. The frame has BB-30 and takes the Ritchey seat tube topper. I might have to build one of these for the shop as a demo to see how it rides.
