Actually, it's not for me, but for a friend who can get a amazingly great deal on a used XS or XXS Time VX Edge frame, but knows that the extra cm+ (or more) will make the bars too high for what he likes, even with a 17 degree stem.

The top bit on the headset is way taller than regular.

Can he use the top bit -- which is smaller -- from the more expensive Time frames?

Can he use a different headset, or different top bit, or different fork and headset, or what?
Are there any other options?

I know this might sound like too much trouble to some, but the price is so great that it's worth looking into.

I also suggested that he suck it up and put up with the extra height, but he knows what he wants.

Thanks
