I’ve had a litespeed mtn bike for ten years and dont think I will ever sell it. I had to make the tough choice between my full suspended GT and kept the hardtail.
The best part of titanium is that it rides like a steel frame but weighs significantly less. If you are looking for a solid bike that will last for years and don’t like the high prices of carbon fiber, this can be a good compromise.
My road bikes are carbon fiber and aluminum.
