Wahine - I put on about 5000 miles a year, most of that on my Kestrel. I have an Ultegra set up (with a Dura Ace rear derailleur). Last year I ran Kysiriums on the bike, and the entire build weighed just over 18 lbs.

I don't think it's too heavy, but I am also a bigger rider - 5'10" and 150 lbs if that makes a difference.

I am looking forward to trying out the bike with the new Zipps on it this season!

Good luck (you won't be disappointed with the Kestrel!).
