Spokes & Nipples
While they aren't very glamorous, spokes and nipples are what really makes a wheel. choose the wrong setup and you may end up with a wheel that doesn't suit your riding style or that won't last as long as you would like.
Spokes
I primarily build with 3 brands of spokes DT Swiss, Wheelsmith, select Pillar triple butted or bladed and for those special builds BERD PolyLight. At their most basic, spokes are just wire made from special steel alloys, that has been formed into straight, butted or bladed lengths, using a variety of forging and stamping process'. There are enough subtle differences between the brands that there are sometimes good reasons for using one vs the other.
In any given configuration, it has been my experience that the DT spoke is a "stiffer" spoke. What this means, is that for any kind of a race or performance wheel, it is usually my go to spoke to help promote that "snappy" feel. When it comes to absolute strength, I feel that the stiffness, also translates into a slightly increased tendency for breaking. It is not a common occurrence, or I (and the rest of the bike industry) would not use them nearly as much. Similarly, that’s one of the reasons I don’t build with too many Sapim spokes,(although there are occasions when they are the right choice) I have just seen too many come in broken on all kinds of wheelsets, for no apparent reason other than fatigue. Whether that is mostly due to the manufacturer or builder of the wheels is unclear, but not a chance I'm willing to take when I have excellent, proven performers in DT and Wheelsmith.
Conversely to the DT, the Wheelsmith spokes have a little bit more give to them, and this has translated into a super strong and long lived spoke. This is my go to spoke for some high stress applications or ones where ultimate longevity is the high on the priority list. *As an update, with the Wheelsmith spokes trending towards unavailability, the new triple butted PSR spokes from Pillar, are excellent for many high stress disc brake applications, bringing an extra thick elbow to the table while still tapering thin in the mid section to keep a nice weight.
Spoke Types
Bladed - they are light, offer excellent power transfer and are a bit more aero; the downside? cost of course, but the DT aerolight or aerocomp are the ones to have. If you imagine a round spoke can flex evenly in all directions, but a bladed spoke resists flexing against the blade, allowing nice ride quality and excellent drive characteristics. By providing nice flat surfaces to hold on to, they also allow much higher tension before "wind up" than a similar weight round spoke.
Butted - Usually double, some spokes have triple butting. This is when the elbow and threads are a thicker diameter and the middle section is forged down to a thinner gauge. These are the standard spokes I like to build with, good strength and good elasticity, which helps maintain long term tension and prevent breakage over straight gauge.
BERD Polylight - Wow, what a difference modern technology can make. These spokes increase the ride quality of any rim combination, and will do astonishing things to the final wheelset weights. Builds are a little more labor intensive, with the critical hub prep, but the end result is something really special to ride.
Nipples
Often overlooked is the spoke nipple, but here too, there are lots of choices which will give you varying results.
Brass nipples (pictured far right) are the basic default choice, they resist rounding off when using the wrong size spoke wrench (unfortunately common in the workshops around the world), they hold up better in wet or salty conditions, especially coastal use on carbon rims. However they are heavier and, well, boring.
There is a large quantity of low quality, poorly anodized aluminum nipples out there, mostly found on OEM built wheels, unfortunately these have created a general misconception that aluminum nipples are weaker than their brass counterparts. In almost three decades of building wheels, I just haven't seen that to be the case. It is easy for many people to tend towards building wheels that are far heavier than they need to be, with heavy rims and brass nipples in an attempt to have the end product last a long time. The unfortunate part of that scenario is that heavy wheels are just not as nice to ride, a few hundred grams may not seem like a lot on paper, but when you are in a situation where you are accelerating them with EVERY SINGLE pedal stroke, I do think it makes a difference. One of the real benefits of a handbuilt wheel is that it can be built to a purpose, for a specific rider, which means optimizing for a long lasting wheel that is as light as it can be for that application. This equates to a better, faster, smoother ride and in many cases involves high quality aluminum nipples.
Far Left - Pace Line and Sapim use a 7000 series aluminum for their nipples, a much higher grade alloy and with dual stage anodizing, that means excellent corrosion resistance. Lots of color choices, these are the nipples of choice if you want traditional square wrench flats.
DT Squorx - This is the only DT nipple I try to use, it is shouldered to work with their rim washers to allow for better alignment when coming out of the rim and has a nice star wrench on the outside for building and truing without having to worry about the flats.
Spline Drive - Just recently re-released, these are often my first choice when it comes to alloy nipples. With 6 splines the turning force is distributed more evenly, allowing for smoother movement, low marring and they are IMPOSSIBLE to strip out. They do require a special spoke wrench, which I include at no charge with all wheels built using them.
