It's Gerard in Melbourne. the lad that you bought the beautiful Tommasini Diamante off. I was reading your threads after googling Tommasini Diamante, quite engrossed no less, cos she that effect on me(see below), when BANG. I don't what to say. I hope Maurrizio can help you, and I'm sure that Irio Tommasini, if he has the chainstays, would fix it too.
I also have a 2005 Diamante which was a remake of the classic, but it is slightly too big. 57cm top tube. it suits persons over 6'1''. It may be 4sale.
But if you get stuck, I have an Tommasini UltraFire (steel)55cm top tobe, and a Tommi GD2 (carbo with 54cm top tube, and a Tommi Carbo Mach 55cm top tube (Titantium with Carbon rear triangle and front forks).
First things first- fix the old girl, as Old Tommasini's never die.
For those who have never been smitten by Tommasini, you just don't know!!!
Glad you're OK, so pick yourself up and get back out there
