Awesome fast bike!!

Love this bike! Worth every penny. Upgraded saddle to a brooks and stem for a longer reach. Also added some carbon fiber R3 rims. Super light! Only bad thing I can say is that there is something inside the frame tube that is making noise but other than that awesome bike.

Incredible

Stunning in the sun. Frame welds look really good. The sizing is a bit off, I ordered a 58 and needed to size down. Which is always a pain, but the return is simple.

Another awesome bike by SBC

I recently purchased a Black Edition II (BEII) and started hitting record times. I sold my 2020 Cannondale CAAD 13 because I was outperforming it on the BEII. I figured I could step up my game on the Undefeated II.

Overall, I'm happy with it. The packaging was good just like the previous bike (BEII). It is different from the BEII (components, frame design, etc.) and is much more bare bones (frame and components... def worth the extra $300). If you're shooting for a daily commuter with flexibility, I'd go for the BEII, but if you are looking for a minimal approach with performance, go for the Undefeated II model. I live on the 3rd floor of an apartment complex and the undefeated is much easier to handle and carry around than the BEII.

Both are great bikes. Do your research and pick what works best for you.

I'm rating the undefeated II at 4/5 stars because the front wheel baring and bottom bracket are making a lot of noise/creaks. My BEII makes nearly no noise. I was hitting record times on my BEII and am performing about the same on the undefeated II, but have cut back a little on my training, which probably has something to do with my gains. The undefeated bike does feel significantly lighter (about 2 lbs do to setup) lighter than my BEII, which is now a daily commuter. I keep the undefeated II model for a minimalist approach and group rides.

I'm running Continental Gator Skins on both bikes. The Michelin tires that come on the undefeated were squishy feeling... I didn't like them at all.

If not for the creaks, clicking (front wheel hub etc.), the undefeated would have a 5 star review.

Some issues, but overall a good bike.

It's a fast bike, and you'll have a hard time looking for a really good aluminum fixed gear at this price. They Black Label is still a better deal, has better tire clearances, and will save you money. The reason I picked this up is because it has a better frame set, and I'm fine wearing out the stock components and then upgrading them. Also the crit geometry is fast and even with my large feet, there is no toe overlap. The stock components are fine, the essor branded cranks and wheels are more than adequate and have held true so far.

I looked through other reviews here and the mentioned 'ticking' from the aerodash crankset, but this hasn't been an issue for me. There is a problem with the stock gearing (48/16) because it leaves only one skid patch per side. So unless the gearing is changed, there will be one spot in the tire that will wear much faster if skidding. Already I installed a 15T from my last fixed gear which is definitely an improvement (5 skid patches). Not too big of a deal because most will gear down or up from stock.

This brings me to my next observation, the dropouts are chromed. WHY. This decreases the friction and I had it slip on me twice. Once when I first got it and rode it, and the second time after I changed the cog to a 15T. The chrome is already flaking, and the dropouts look like they're stainless steel. So why bother chroming them? It doesn't look good after the wheel slips and destroys the chrome. And anesthetics are the only reason they would be chromed.

Very good but needs some improvements

Very good bike, like really good it is lighter than my road bike and the components are high quality, however the rim brake surface that is normally black wears off easily and the saddle wasn’t that good but truly a good bike, with 100+ miles on so far everything is working perfectly.
