Hi Becky, I had been wondering if the Bontrager I am using is too wide (it's 150 whereas the Arione is 132). I did sit on the butt-ometer for a fitting and was inbetween sizes so I sized up rather than down to the 140. I think the Aspide Glamour would be too wide at 155. I do like the look of the Vitesse but it is also 150 wide - maybe I need to go and look at a Vitesse & Aspide and see for myself.
