The Truth About Aero Wheels

Have you ever thought about why the other wheel companies charge so much? It seems like highway robbery, and we agree. The marginal differences between these three wheels are so small, only the marketing department can “claim” there’s a difference. The truth is, upgrading from your stock wheels to new aero wheels will be a tremendous speed upgrade, but trying to tell the difference between them, well… look at this chart and see for yourself.


What does this even mean?

Raise your hand if you've noticed that every wheel company has a chart that looks something like this, which "definitively" proves "without a shadow of a doubt" that their wheel is the fastest. Here's the truth: you will never race in a wind tunnel. Sorry to burst that bubble for you. Each course, each day, and each turn you make changes the wind angle, so why obsess over these tiny differences that really amount to what? 70 seconds over 112 miles? Maybe for the very top world class pro triathletes the time savings is worth considering - but then again, they aren't paying for their own wheels anyways.

The Direct Advantage.

direct to consumer advantage

This most likely won't be the first time you buy something online. It's the age that we live in - and we think it’s a great thing. We sell our wheels directly to you because it allows us to deliver the highest value at the lowest cost. Our competitors have to pay all the middle men along the way - not to mention their sponsored athletes and glossy ads. Going direct also means that we can handle, fix, and resolve any problems you may have. You don't have to go to your bike shop, which then says go to the manufacturer, who then sends you right back to the dealer. We are the decision maker, and you better believe that we want you to be happy.

The other advantage of being the manufacturer is that we save you money, time, and hassle when you buy from us. Unlike anyone else, we offer: Tire Installation, Cassette Installation, 30-day Trial Ride, Free Shipping both ways, a 3-Year Warranty, and 6 month Payment Option. When your wheels arrive, you can potentially mount them and ride straight out of the box.

A holistic approach to speed

We all want a faster bike split. The truth is that you can buy speed for the bike course. Mounting some super slippery aero wheels on your bike will put you on a very fast track to a PR. But let’s be real – you could also buy: an aero helmet, aero bars, aero base bars, special race kits, aero hydration mounts, coaching, and a variety of other things out there. All of these are a couple hundred bucks each and would potentially give you about the same speed upgrade. Now, the beauty of this is - if you skip out on the big name brand wheels, you can have all of this AND still get the same aero wheel upgrade you wanted in the first place by purchasing a set of Karbon Speed wheels. Now you see where we're going with this?

How much is 100g anyways?

There are some that will go on and on and on about minor weight differences between wheel sets. Trust us, we take these calls on a regular basis. We're not sure why some folks will obsess over 30, 40, or even a 100 grams. Have you ever wondered what the big deal is? Well here is a reality check for you. You know those gels you take with you on pretty much every ride? Sometimes one, maybe three... hold up - there's your difference right there. Two gel packs weigh in at about 100g; now are two gel packs worth almost $1,000!? If you ask us, they better be pretty damn good gel packs (and they're not, we already checked - see above). Plus, we've never heard anybody say, "Wow, I would have had a great race today if it weren't for those two gels in my back pocket weighing me down!"

Don't ever skimp on quality.

With the XA we start with in-house prepreg. How many wheel companies can say they actually do the prepreg themselves, in-house? Not many. We get the raw carbon fabric from Toray – the leading supplier of ultra-premium carbon fiber in the world. The Toray T-700 Carbon Fiber is then processed in our factory where we impregnate it with resin (hence the term “prepreg”) using a 100% automated process to ensure the highest levels of quality control and raw material purity. Our new prepreg is then moved in our factory to where it begins to take the shape of a Karbon Speed rim in one of our four molds. It is more expensive to have your own molds, but it is the only way to produce a quality rim every time. Without our own molds, we couldn’t offer our 3-year warranty. Once the rim is set, coated, sanded, and passed quality control we use a laser cut decal to emblazon Karbon Speed into the rim with a clear coat finish. Stickers just seemed cheap.
