Significant upgrade for a great price

Other than wheels, this crankset is the most significant upgrade you can give your ride for a very reasonable price. SRAM produces high quality performance parts and the fact these are part of the "track standard" should tell you something.
With that our of the way, these are my favorite cranks for several reasons:

-Stiff as hell. When you pedal, there is NO FLEX or pause... you move forward.
-The GXP bottom bracket is super easy to service yourself and buttery smooth with no creaks or pops as you put the hammer down or lock up a good tire ruining skid.
-Installation is very beginner friendly. I like to learn and service my bike myself and you literally need grease, a BB wrench, and Allen keys to install this set up. Too easy
-They have the magic BCD sizing you need to throw on all those boutique after market chainrings that we all love...don't roll your eyes...you know you love them too
(don't forget the chain ring bolt colors !)

If you're on the fence about this crankset, don't be. You'll get over the stress of clicking submit order as soon as you get that glossy box of joy with "SRAM" plastered on it at your door.

After the worlds supply of Omniums dried up, here comes SBC with the hook up. I can only assume these were superseded back stock, but get them while they last. Beware of frame clearance and chainline, but if you’re after Omniums, this is the only place you will find them. Until you can’t.

Everything was good except the packaging. Shipping times were ok but when I received the crankset it wasn't packaged very well. It was banging around in the box. Other than that I don't have much to complain about.

Great crankset. Very solid. Only 165mm set I could find online anywhere. Not sure if they come with a box or not. Cranks we’re just loose in box but protected/packed nicely. Nothing was scratched or damaged upon receiving. Overall satisfied.

Love it!!!

The SRAM Omnium crankset w/GXP bottom bracket are definitely pricey, but I will say they are definitely well worth the cost! It is 100% better than the cranks that come stock on the 4130 series. I noticed instantly the smooth feel of the ride as soon as I changed them and it is made everything better on the feel, including sprints, climbing, and sustainment. It was extremely easy to install and definitely bring a much cooler look and feel to the overall aesthetic of the bike. So far, I have had them on my bike for a couple of weeks now and have loved every ride with them! I would highly recommend the SRAM Omnium crankset to anyone who is looking to upgrade. Definitely worth the buy and you won’t regret it.

I was glad to get these set of cranks since they’re being discontinued. If I ever need another set know where to go if it’s still available.

Very stiff and responsive

I’ve given these quite a few tries on a few different bikes so I knew I wanted these but I was pleasantly surprised when finally getting the chance to put this crankset on my own bike
Probably the most responsive crankset I’ve rode giving lots of really smooth feeling skids these had been pretty hard to find and I assume that’ll continue to be the case once states supply runs dry so I’m glad to have found them here when I did also the shipping was pretty quick

Great feel, great looks

The Omnium crank with the GXP bottom bracket are probably the best upgrades you could give your fixed gear frame (given that that's pretty much all the mech you have on there :) ). I'm going to add this review on the GXP BB page too because I think it's just as worthwhile as the crank.

Together they have a really tight and clean feel and appearance to them. I like the Omnium crank arm's straight line and prefer it to the curved arm that the SRAM crankset that came stock on my Contender. I can't claim that I personally feel a huge difference, but that could be because I also changed the sprocket at the back at the same time I installed this crankset. Omniums are the standard for track racing though.

Easy installation, they feel great, and look gorgeous on a bike.

Omnium Crankset Aweseom

This review is actually about my entire "State Bicycle" experience. I purchased the "Undefeated" with the Omnium Crankset and have the ultimate "street warrior." (Mind you I am 56 and just got back into biking after a very long hiatus! The Omnium with the sleek and responsive "Undefeated," makes me feel like a kid as I attack the streets! The Omnium adds another level of "power" to each revolution! Maybe it just looks cool..LOL! (Which it Does!) Well worth the upgrade!
