Which one is better suited for durability and lifespan of a ti road frame??
thanx in advance
In general, 3/2.5 is a better material for main tubes. While 6/4 is generally lighter, it is harder and therefore can be more brittle. Many companies use 6/4 for things like dropouts. Also, for a long time there was no such thing as an American made seamless 6/4 tube, but I think there are at least a couple of frame manufactures using them now.
Thank you!
