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.

Buttery light with smooth hints of power

My fixie of five years decided it was time to enter bike heaven. Cue: new bike time! My housemate had just picked up a State Bicycle so they were on my radar. Most of the fixies from $300–$900 all run the same components. You are literally paying for the quality of the frame and the logo on said frame. I knew I wanted to get something with far better quality components. I’m hard on bicycles and I ride a lot. Wasn’t looking at a setup that would need constant upgrading. I looked at custom and it was going to cost over $2k for a bomb setup. No bueno with times like these [2020]. I ended up narrowing it down to the 6061 and the 7005. The Undefeated just seamed like it had better overall components than the Black Label and really not much of a price hike. Unfortunately due to manufacturing pauses, there wasn’t much I could customize due to I assume availability issues when it came time to pull the trigger. Had to order the Brooks B17 saddle online and I couldn’t choose the riser bars when picking handlebars. Bought those additionally (via PayPal credit, 6 months interest free payments no less) and then sold what I didn’t use on Craigslist within a day. Easy as! Been riding it non stop for the last 3 weeks. First thing about this bike is it is light! Really light! It’s smooth and feels fast, average about 18mph while my old bike was 15mph. I put that down to lightness and also the drivetrain. It’s perfect for flats as well as hills. I do live in LA though, in SF I would want an easier ratio. I have heard clicking was an issue but if you use White Lightning on the chain and make sure there is ever so slightly some slack, nothing at all and it puts the power down hard! The carbon fork soaks up the giant cracks like butter. It’s smooth. The paint job? Wow! Was dubious to get a black bike but damn, when the light hits it, you’ll have people high on ‘shrooms yelling ‘double rainbow’. I absolutely adore this bike, complete badass of a bicycle. A few things to take note. Gatorskin 28s do not fit the front fork. When on the bike, it hits the inside of my fork, even more so when making a turn. Honestly, not even sure 25s would make much of a difference. Stick to 23s. 28s on the back are fine. Which brings me to my next point. The chain was very tight initially. Even now, with it stretched out, I still can’t quite fit the Gatorskin 28s on the back. Not a huge problem but something to be aware of if you are thinking of upgrading the tires upon delivery. The brake system (levers, cables, brakes front and back) are generic and pretty horrible. I bought an Odyssey Medium lever (BMX), Odyssey Slic cable and a Shimano Ultegra BR-R8000. Brakes are smooth and stop you in a one finger pull. The microfibre seat is pretty grippy which isn’t great for chafe, as in long rides. Do yourself a favor and get a Brooks B17. I accidentally stripped the chain tensioner bolt on one side, tried to get it with pliers and it broke off and is now stuck in there, which reminds me, some of the hardware is quite soft. Probably going to upgrade to better grade hardware (all black too) eventually. Only small cons though. The pros far outweigh and damn, can’t wait to get out there and ride it again. Actually that time is now. L8R!

SWEET BIKE

This bike is rad - even has rainbow SPARKLES on the frame which adds to the awesome. Was delivered quickly and without any damage.

Crashed but couldn’t be happier

Love this bike soo much less then a week after getting it some guy pulled out on me and I smashed into him at about 20 mph bike got banged up but for those 4 days I had it brand new it was the best bike I’ve ridden.

Sweet Frameset and Wheels, surprisingly meh components.

First fixed gear, but not my first bike. I bought this because the 62cm Raw black label was out of stock. Stem and drivetrain are pretty clicky under force. I’ve heard from other people that this drivetrain is clicky for them as well. The white bits look cool but get dirty easily. And you’ll probably replace them anyway. Bike is stupid light, and pretty stiff. Climbing and sprinting on this bike is beyond fun. Ran brakes for a day but the levers slipped on the handle bars. Also, I regret not buying the pedals and straps from SBC directly( that’s on me obviously). Even with the clicky drivetrain, all in all, well worth the money. It’s genuinely fun to ride, and for the tall people, it doesn’t look weird as a tall bike. And it’s terrifyingly fast.
TLDR; Buy the bike and you’ll get over any issues you have with it instantly.

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

Cool bike

Overall I like the bike after I did some tweaking to it because from their assembly line the chain was way to short so I had to go buy a new one and also the brakes they give with the bike is useless, they don't even fit the handlebars. I don't use brakes but what's the point of giving brakes if they don't fit? I expected better attention to detail from a bike at this price point, so I rated the overall experience 3 stars.

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).

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

Fast Commuter Bike

I owned the previous version of the Undefeated that came with the Sram Omnium Cranks, and sold that bike cause I (mistakenly) thought I wanted a more "commuter" style bike. A year later, sold the slow commuter bike (not a fixed gear) and got myself the Undefeated again. Only negative is The new Essor USA Aerodash Crankset squeaks when I am peddling hard and are definitely a downgrade from the previous Sram in quality. I am not disappointed as I was aware of the downgrade via other reviews before purchasing. Would have happily paid extra for the Omnium as an upgrade, but the Essor is good enough and not worth it for me to spend the extra on a whole new crankset. Overall, I highly recommend the Undefeated. It is a fun bike to ride. Yeah, per the pic, I have an unusual set-up with aero bars and a tall pannier bag directly behind, but it is pretty aerodynamic, gives my wrists a break, and unlike the other bike I mistakenly thought I wanted, this one goes very fast with my 13 tooth cog, even when I have my laptop, change of clothes, and tools in the pannier (and not in a backpack weighing down on my soft tissue for an hour each way).
