Beautiful finish and styling. More importantly the bike is fast and comfortable. I highly recommend the Brooks seat upgrade and going with the bullhorn handlebars; though choice of handlebars is more of a « what works best for you » decision
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).
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
The Undefeated II - Black Prism Edition is a such great bike and also has an awesome color.
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 II - Black Prism Edition
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.
This bike is rad - even has rainbow SPARKLES on the frame which adds to the awesome. Was delivered quickly and without any damage.
