Handlebar size options I was given few options to choose the handlebar size for my future road bike. The frame size is 60cm but for the handlebar I have these options:

40x90,40x100,42x100,42x110,44x110,44x120

I measured myself from shoulder to shoulder and it's 44cm, so there are only two options for me. The problem is that I don't know what the second number mean.

The bike is for daily use and some events/triathlons, but most of all is for daily use.
Assuming these are Drop handlebars, the second dimension would be reach or drop.

On the other hand, as you're buying a complete bike, not just bars, the second dimension is very likely to be stem length.
