New to the forum here so I thought I'd introduce myself and my budget WW (to me at least) project I've been working on slowly for the past year.
This is my first proper road bike and I was on a tight budget at the start. It began with me finding an great deal on a donor bike with nice, new Ultegra 6700 components but with a cracked cheap Carbon frame. So I bought the bike and swapped in the broken carbon frame for this Nashbar Carbon/AL frame that at the time you could get from Nashbar for $150.... I saw good reviews on the site and figured it'd be a good temporary solution to use until I found a better frame. I even sold the cracked Carbon frame on ebay for about $80 so it brought down the cost of the initial build even more.
The initial bike built up with the donor parts ended up around 18.5lb... which is super heavy for this website's standards and I quickly caught the Weight Weenie bug and started upgrading.
A year later I'm at this point and here's what the bike looks like:

Full Current Build list:
Nashbar AL/Carbon integrated frame
Carbon Fork from Bikeisland.com
Specialized Toupe Expert Saddle
Omni Racer Zero set-back carbon seat post
KCNC C7 Brake calipers
Yokozuna Cables and housings
Stradalli carbon bottle cages
Ritchey Pro Bars
Ritchey Pro Stem
Fizik bar tape
FSA SLK Light Crankset and Megaexo BB
Ultegra 6700 Shifters/derailleurs
Ultegra Chain
Ultegra 11-28t Cassette
Speedplay Zero pedals
Farsports 50mm Carbon Tubulars
Continental Sprinter tubular tires
Total weight: 15.70 pounds or 7.1kg
I always intended to replace the frame with something nicer but so far it's been holding up very well over the past year. I think I'll probably get something new for next spring but the Nashbar frame should be fine through the winter.
I know it's not super lightweight compared to most of the builds on this site, but it's my first go and I was on a budget. I figure that if I were to upgrade to a 1,000g (or less) carbon frame in the future, it'll immediately drop the total weight into the low 14s which will be nice.
Thanks for reading!
