A well spoken change!

Since we started Boyd Cycling 10 years ago, one thing has remained the same in all wheels. We had always built with Sapim CX Ray spokes. The CX Ray is widely considered one of the best spokes on the market and we’ve built tens of thousands of amazing wheels using those spokes.

So, let’s not mess with a good thing. . .right? Wrong.

Well, it took a lot to change our mind, but for the past year we have been testing the Pillar Wing 20 spokes and there are enough benefits to where we just had to make a change if we wanted to keep making the highest quality wheels.

Now, all spokes start off as a steel wire. The best spokes are made from Sandvik steel, and the steel for these spokes is made in the same factory. It’s then pulled, shaped, and treated to make the spokes we are used to seeing. Having toured multiple spoke factories, it’s a pretty amazing and automated process as most places are pumping out tens of thousands of spokes per day.

Spokes come in bags of 500Pcs

Spokes are actually one of the best ways to dictate the stiffness of a wheel. Of course the wider the hub flanges, the better the bracing angle of the spokes. However, spoke thickness really affects the stiffness of the wheel; a larger spoke will deflect less and will cause a stiffer wheel. This often comes at a weight and aerodynamic penalty. One of the primary differences between most bladed spokes and the Pillars is the wing shape the Pillar takes. Most bladed spokes are flattened, leaving a very thing cross section that can deflect more.

Cross section of the Pillar wing spoke. 1.21mm thick

Cross section of a Sapim. 0.88mm thick

 

 

 

 

 

 

 

 

With this wing shape, and thicker cross section we are seeing less spoke deflection, which builds up a stiffer wheel. In fact, on a fully tensioned wheel, the drive side spokes deflect .6mm less with our tension meters to read the same kilograms of force.

There has been wind tunnel testing which has shown both the Pillar and other aero bladed spokes to be equal.

We have approximately 20,000 spokes on hand at any given time!

The big decision influencer:

Everybody hates a broken spoke. While we do our absolute best to get consistent tensions, stress relieve the wheels properly, and use the highest quality products, the wheels are still going into rough environments. Some people are putting tens of thousands of miles on their wheels. A broken spoke is an inconvenience, and something we have been fortunate to keep to a minimum. However, we know it’s something that has a chance of happening. This is why we build with external nipples, and standard J-bend spokes that are super easy to replace.

If we made a spoke change and our customers started having broken spokes, it would fall back on us for making a bad decision. So we tested the Pillar spokes under 4 different pro teams last year. We built all their training and race wheels with the Pillar spokes (and didn’t tell them). Under 40 different pro priders, riding and racing a full year, we were pleased to see zero broken spokes (that weren’t caused by crashes and getting skewers through wheels).

This is because of the new reinforced elbow on the Pillar spokes. All other double butted spokes have thick ends and a thinner middle section (for example 2.0mm, 1.8mm, 2.0mm). On the Pillar Wing the bend of the elbow, which sees the most amount of stress, increases to 2.2mm thick. This adds no weight, but makes a much more durable elbow on all the spokes. This image shows that elbow reinforcement.

 

To summarize (TLDR): 

  • Same Sandvik steel as before
  • Thicker cross section
  • Same aerodynamics
  • Same weight
  • Reinforced elbow
  • Stiffer wheel

We have been happy with the change, and we feel like our customers will also appreciate the better stiffness and durability.

    Is the cross section symmetrical, or teardrop with inner and outer spokes?

    The cross section is symmetrical.
    The profile with dimensions looks like this:

    I bought of set of Altamont wheels about two weeks ago. Are they built with the Pillar spokes?
    Just curious, wheels roll great.

      You can check the spokes. If the have a P on the head of the spoke, then they are the Pillar ones.
      If they spell out “Sapim” just below the elbow. . .then, they are Sapims.

    As good as the Sapim CX Ray spokes are this change to Pillar wing spokes looks like a good change that was well thought out.

    Hi
    Boyd

    A customer since 2010 way to many wheels.
    One of the reason I’m a Boyd fan is we never have to true a wheel , never worried about Broken spokes does that still happen?
    I have wheels that never had a wrench on them in 20,000 miles.
    Are you saying the Piller spokes are heat treated and pre stressed like Spaim
    Thanks but I’ve never been a fan of DT, Piller,etc

      Yes, the process is the same. This is not a change that we made without a lot of careful planning and testing.
      But I am super happy that you have ridden so many miles without ever needing to touch the wheels. That will not change!

    Are we able to get spares for our existing wheels in the CX Ray or can we just as easily swap in a Pillar if one breaks? I have a set of Jocasse that I’d love to have a spare couple spokes.

      The Pillars will be interchangeable with the CX Rays. Actually, any 14 gauge J bend spoke will work for replacement.

      Just keep in mind that with different spoke dimensions they will all have different deflection rates to calculate the same kilograms of force.
      So, you would not be able to use the same numbers on the tension meter when using a different spoke because of the different thickness. You will be able to tension them to the same kilograms of force though.

    This design looks good. cx-ray is legacy tech and had to be surpassed some time.
