THIS BIKE WILL RUIN ALL OTHER BIKES FOR YOU

I unpackaged this bike and instantly understood what King Arthur felt when he unsheathed Excalibur from the stone. When I saddled up this beast power rushed through my body from my handlebar mustache to my cuffed jeans. I signed a deal with devil and threw away the brakes that came in the box. When I did so a sleeve tattoo appeared on my arm, I think I leveled up to a new type of hipster.

Beautiful, fast, all around badass

I’ve been drooling over this bike since the last models come ways, so when i got the itch for a new bike I had to go with the undefeated 2. I ordered it through my lbs and when I went to go pick it up I was floored. This thing is gorgeous. I put some 25mm Vittoria corsas on it instead of the stock 23s because the roads in my town are awful. It rides like a dream even on rough streets now. The 46/18 ratio is perfect for me since I live in a more flat area. The aerodash crank set is pretty damn sweet too. That thing is stiff! I swapped out the seatpost and saddle and it’s been pretty great to me so far. Definitely recommend this beast

Straight up beast

I’ve been in love with the undefeated models since the previous color way, so when I decided it was time to get a new bike I considered a few others but ultimately decided to go with the undefeated. And man I’m glad I did. I went to my local bike shop and had them order me. When I went in to pick it up, I was floored. The paint job on it was absolutely beautiful. I went with some 25mm Vittoria corsas over the stock 23mm tires because the roads in my town are awful and 23’s just wouldn’t cut it. The aerodash crank set is amazing and stiff as hell. The 48x16 ratio is perfect for the flat town I live in. The bike is fast and super light. All in all this bike is absolutely amazing and beautiful. I would recommend the undefeated 2 to anyone who wants a badass fast as balls freedom machine. Buy it, you won’t regret it

Undefeated 2

Absolutely love the bike! It's my first fixed gear so riding it is taking some getting used to but I'm having a blast doing it. The black prismatic colorway is absolutely stunning in person. My only complaint is that the stock aerodash crankset apparently flexes under power and creates an annoying clicking noise so I had to pretty much immediately upgrade to a sram omnium set (which I had planned to do anyway but just not so soon). Other than the cranks though, the bike is a blast to ride and I'm stoked to have gotten to support an Arizona brand (I'm originally from AZ but living in VA).

Love It So Far!

Ive only ridden about 100 miles so far but this bike it very fast, comfortable, beautiful, and light. It has gotten a lot of compliments, too. The paint is super sick and I can’t wait to do some more rides.

Great bike!

Bought this bike after my Bianchi Superpista was stolen on a great sale. I’ve loved it so far - it’s just as light as my previous build and zippy. Comes with some high quality parts. Nice color, too. Thanks!

So now after few weeks i can finally leave review. At beginning i had some issue with scratched frame and not true front wheel and i complained about it, they send me brand new wheelset to make me happier what is awesome and i appreciate it so much ! Its the greeeat bike, smooth, fast, light !!!! Fun to ride. Its not the most comfortable bike but its race machine. First think what you need to change : tires, saddle. Stock tires after few strong skid will be ready to throw out. Saddle after first ride will tell you to replace it. Generally after getting better saddle and gatorskin its awesome bike. Totally recommend State bicycle co.

The Essor USA Aerodash Crankset is built with 7075 aluminum and uses an external bottom bracket to ensure maximum power transfer, while the seamless construction promotes smooth airflow over the crank for greater aerodynamics.
