Fast in a straight line, quick around corners

I'm in at 18.14 pounds with pedals, a bottle cage zip tied to the seat tube. I have it with phil wood hubs laced to h plus son archetypes, 3T carbon bars, 3T 120 alloy stem, edge seat post, sugino 75 crank, some Colango labeled brakes. I have it geared for a moderately hilly area. If you like the geo of slammed front, you'll love this bike. It is a bike that's meant to ride fast, not necessarily set up for chilled out shooting the breeze. I love this bike.

SO SICK

Been riding this frame for a few months now, and HOLY SHIT I love it. I’ve put it through some 100+ mile, 10,000+ vertical foot days, various lesser climb-heavy rides, and a lot of courier work, and it’s handled it all admirably. Prior to this, I was on an Engine 11 Crit D. I find the Undefeated to be stiffer and more responsive, and much more stable and confidence-inspiring in corners (which comes in handy when descending mountain roads brakeless or cutting through traffic). Oh yeah, and it wheelies reeaaaal good, and that sky blue paint job is hella cute. Side note: be sure to pay attention to the top tube measurement, as it is kinda long compared to the seattube size. I rock a 54 in most other bikes, but this 52 fits me perfectly. Anyway idk just buy this thing you’ll dig it.

The carbon fork absorbs well on the street and rough terrain. The frame set is very light and yet easy to control. The paint has a prism effect that shines and sparkles day an night, which was a surprise.

The undefeated frame is stupid light

I got this frame replacing my state core line steel frame. I can't even begin to tell you the differences. The main and most obvious is the weight difference. I not one to leave stock parts on my bikes. My core line is pretty much all changed from when I bought it. When I bought the undefeated I just bought the frame with the fork. I have my own tools and do my own work on my bikes. I swapped all my parts over.

Easton carbon road bars
Zipp sl 90mm stem
Zipp sl carbon 31.6 seat post
Shimano ultergra r8000 brakes
Wabi sub15 wheel set
Specialized Sworks romin evo saddle
State black label cranks with 7075 48t chainring
Specialized Sworks 24c front, 26c rear tires

On my core line I could fit 28c tires with the state carbon fork, but on the undefeated i found it common that a 28c won't fit. If the 26c fits in the fork I'll run that but if not the 24c will fit. My bike built is like stupid light. I don't have an exact weight but going from steel to high grade 7005 aluminum was a dramatic difference. The frame and carbon fork alone weigh 4lbs 9oz. The steel fork on my core line weighed almost 2.5 pounds...that was just was fork.

I recommend the frame set, or buy the complete if you just want to ride when you get it.

Nice 55cm Lightweight Aluminum Bike Frame (full carbon fork)

I was looking for a lightweight frame for a new bike build. My goal is to keep the build under 20 lbs (shooting for 18 lbs). The frame arrived in great condition. The bottom bracket threads were perfect. The headset (included) fit perfect. One note on shipment. The zip-lock bag for the headset was almost opened because the zip portion was not sealed with tape. The headset was in a bag and taped to the rear part of the frame. I just want the state bicycle team to know that the bag needs tape at the zip section to prevent popping open and maybe losing some parts. Anyway, I'm almost done with the build. Still need pedals, bars, bar grips, front brake and brake lever. It's weighing 15 lbs up to this point. It's going to be close! Oh, the black glitter/sparkle paint is awesome! When I finish I'll send you guys a pic with complete build details if you like. Have a great day! I haven't cut the fork tube yet, so it looks extra tall right now.
