I think you're right but it does have a carbon fork and I've read repeatedly that a carbon fork is enough. I've also read that an aluminum frame is only marginally heavier. I'm not sure. This bike weighs 23 pounds and it sure would be nice to see it below 20. Can't wait to ride one. I did finally get to ride the Giant Fastroad several days ago but unfortunately it was the aluminum frame (Sport?) I liked it o.k.....maybe not as much as a Sirius I tried, but I think any of these nice hybrids would be a good choice once it's dialed in to individual preferences. Finally, I think the Giant has the best cosmetics I've seen but that's personal preference too.
