I bought this 2003 Kestrel frameset from Ebay. I had previously built a 200CI for resale (a bit too small for me) that was a wonderful ride. The wheels are relaced 600 tricolor hubs with new rims. I used Dura Ace derailleurs, 9 speed cassette, and bar ends. The crankset is a compact FSA. I estimate her at just under 18 lbs.
I haven't ridden her yet, I wore myself out this morning with yard work. I may ride her to work tomorrow.
