Because Record is better quality & lighter than anything else. I ride my bike a lot. It is my car ( I don't drive & have no intention of driving). Therefore I can justify spending a lot on something which I am going to use to get from A - B quickly, and which I am also going to race upon.
I have never ever retrospectively questioned why I upgraded anything on my bikes, I always feel the performance benefits & know that it was well worth spending that money.
How much do you cycle Daz? From the sound of things you spend sh1tloads on a bike, so you should understand where I'm coming from.
