Had a Litespeed Vortex, the new one with the "diamond" style tubing, always wanted one, they look great and the effort that went into making one of these frames is extra ordinary. Waited ages to get the right one. Finally got it and it was rubbish, it flexed that much that it used to "ghost shift" all the time, under braking it was unstable also. Had it for just under a year as I "wanted" to love it, I changed everthing on it to cure the problem, spent a mint and it was the same. Its gone now but still love the look of it. My mate had the same model and cracked it near the BB. NEVER EVER AGAIN !!!
had a litespeed tuscany which was a great bike, sadly sold. Replaced later by a litespeed siena and second the comments above, really comfy frame with carbon stays/carbon fork. lovely. Now also sadly gone.
