The pulse has better tubing, a fancier fork, is made in the US, and will cost a lot more.

About a month ago, I had the choice of getting a complete GTB at a decent price or an incomplete Pulse for twice as much.

Went with the GTB. If you're riding on the street, all the "weight savings", " extra stiffness", and other silliness make zero difference.

If you're racing, there are better, newer options than a Pulse.
