3AL/2.5V is the 'standard' tubing used by a majority of the builders. Whether a bike is rigid/stiff or noodly will depend on the specific tubes used and how the bike is constructed. By specific tubes I mean that 3AL/2.5V is merely a type of titanium. How the tube is made; thin walled, thick walled, butted or not, shaped or not will determine, along with geometry and construction of the bike itself, the characteristics the bike will posess.leon2982 said:I see Litespeed announced a new lower-priced frameset that uses 3AL/2.5V titanium tubing. Just looking for comments on this tubing in terms of how rigid/stiff these new frames might be.
longcat said:Having worked with both alloys (non bike related) I would say the 3al2.5v is better suited for a bike frame, its easier to weld, its easier to machine, its tougher, and the difference in strenght is minimal, if you break a 6al4v frame the 3al2.5v frame would have died too. and vice versa. I would choose 3al2.5v because its more forgiving, so the welder dont have to be as good. If I could choose I'd choose sandvik 3al2.5v, but thats just me, the difference is not important to me if done correct, I doubt I would feel it, and I highly doubt it would make a difference in a crash either way. I would go with the cheapest one.
Marketing hype? Collaboration with NASA? C'mon.Juanmoretime said:Litespeed always made certain models from 3.25. It must be the new and improved version that they played classical music for while welding and hugged it every day tell the tubing that they loved it. Don't get me wrong. Litespeed builds nice frames but the statement sticks of marketing hype.
