    name that columbus tube set

    Musing on the differences between tubing materials, particularly high strength steels and ti. Have a Litespeed ultimate 1999 and used to have a Bianchi top end frame from the same period. Loved the rides and if I were to buy a new frame, would likely buy something similar.

    The Bianchi IIRC used a Columbus tubing set called Focus was very high strength with thin walls. Down tube went from a vertical ovalizd shape at head tube to horizontal ovalized at bb. Refresh me on the tube set. It's old enough a web search doesn't give any results. I may be misnaming the tube set name.

    By '99 Bianchi wasn't using much Columbus tubing having sort of switch to custom and Dedacciai tubing. I'll have to dig a bit to see when it started but around that time Bianchi was using a hugeish DT with differential profiles and called it their MegaPro design. Top of the line frames came in MegaPro, MegaPro L or MegaPro XL depending on the type of material used in the frame.

    Unless you have pics to post for a possible ID I would wander around BikePedia and see what you can find.

    Here is a '99 MegaPro XL Titanium frame. Depending on the year and model some DTs tend to look bigger.

    I believe the OP may be refering to Columbus Foco which was a triple butted tubeset using thier ultra-strong Thermacron alloy. Non-butted sections were 0.4mm and claimed tubeset weight was 1112g, making it only marginally heavier than Genius. There was an even thinner Ultrafoco tubeset.
