In the graphic above, you can see the cross section of one rim or hoop. This can sometimes be helpful when building a rim and hub combination you have not worked with before. If you are having trouble finding what your rim's ERD is, feel free to give us a call at the shop.
Spoke Offset : Not all rims have the spokes aligned directly on the center line of the rim. Because the hub center to flange measurements are different from the drive side to the non drive side, the spoke bracing angle on each side of wheel can be slightly different.
To help combat that and in turn make it easier to build the wheels with equal spoke tension from one side to the other, rim manufacturers often offset the spoke holes to one side of the rim. Some rims feature a 0 mm spoke offset, while others might feature a 3mm spoke offset for example. Spoke Count : Just like we said before, it's important to make sure the spoke count for both the hubs and rims are the same.
If you are looking for a specific rim that for example is intended for downhill use, you may be limited to only one spoke count option. When it comes to hubs, the same hub shells are usually offered in multiple spoke hole options. Radial vs. Radial Pattern : A radial lacing pattern, often referred to as 0-cross, sees each spoke move from the hub to the rim without crossing another spoke. Radial lacing patterns are commonly used on the non drive-side of road racing wheels. Because each spoke goes directly from the hub to the rim, the radial pattern uses the shortest and therefore the lightest spoke possible for a given wheel size.
The radial pattern can be also be seen on rim brake road wheels. One cross wheels are stereotypically built just as much for aesthetics as they are for weight savings. You can find a 1-cross pattern on handmade bikes that aren't designed to be ridden hard like you would a gravel bike or mountain bike. A 2-cross pattern can be found on 24 hole mountain bike and cycle cross wheels.
A 3-cross pattern is one of the strongest ways to build a bicycle wheel and is common for 28 and 32 hole mountain bike wheels. Spoke Length Calculator Now that you have all of the different hub flange diameters, hub center to flange measurements, the rim's ERD, the rim's spoke offset, and the spoke count, the best way to determine the spoke lengths needed for your wheels is to use a spoke calculator. Straight Gauge Spokes : Straight gauge spokes are the same gauge or width the entire length of the spoke.
A majority of straight gauge spokes are 2mm or 14 gauge and are used on bmx or mountain bikes where saving weight isn't your primary concern. Because these spokes are all the same thickness, they provide a bit more stiffness and are cheaper to manufacturer. Example - DT Swiss Champion. Single Butted Spokes : Single butted spokes feature a thicker section at the neck of the spoke, closest to the hub.
This gives the wheel additional strength, an even stiffer feel, and is best used for heavy duty applications. Single butted spokes are generally heavier than straight gauge and double butted spokes. Double Butted Spokes : Double butted spokes taper down in the middle of the spoke, reducing wheel stiffness without compromising overall wheel strength. Sometimes a wheel that is as stiff as possible isn't the best thing. Having a wheel that is more compliant helps the bike track the ground, giving you more grip.
Double butted spokes are lightweight and typically more expensive to manufacturer. Aero Bladed Spokes : Bladed spokes are designed to be more aerodynamic, allowing the spoke to cut through the air. Bladed spokes feature a flattened middle section that runs a majority of the length of the spoke and are commonly found on road and time trial bikes. Straight Pull Spokes : Straight pull spokes do not feature the same traditional J-bend hook at the end of the spoke but instead a straight flange.
Straight pull spokes require a dedicated straight pull hub and are designed to eliminate the weak point on the hook feature on a standard J-bend. Most all DT Swiss spokes are also offered in a straight pull option. Find the right information for your particular fork The Santa Cruz V10 we are looking at here uses mm rear hub spacing. Make sure you know the rear hub spacing on your bike Here is a breakdown of all of the dimensions for each Santa Cruz Reserve rim offering pulled from Santa Cruz's website Now that we have all of the appropriate information for our Industry Nine hubs and Santa Cruz Reserve DH 29 rims, we can starting plugging that information in to the QBP spoke length calculator we mentioned before.

I'll be paying a visit tomorrow. Thanks for the information — Rusty. Ray: If you've broken 4 or more spokes, then that is a likely indication that there is a problem with the rim. A smart shop will not rebuild a wheel using the old rim, as there is no way to guarantee your work. And if you replace the rim and soles and rebuild it, that is the same as replacing the wheel.
Where do you live? Just curious — zenbike. Rusty getting a hand built wheel is definitely worth the money. They don't even have to be that expensive, but the difference is really noticeable. Every new bike I've had I've trashed the wheels quickly and then bought hand built ones that then last a long time. The story might be different for really expensive bikes, but certainly on anything midrange and down they seem to be useless. The shop I took it too replaced all the spokes with stainless steel spokes.
He told me the original spokes were cheap ones. All is well now and he fixed a couple of other annoyances along the way that the other shop had ignored. And I live in Utah. Last rebuild was in or so there has likely been some inflation. Show 1 more comment. Hope that helps. No problem. If you're happy with the info, please accept this answer.

These factors come into play with the general question. The sales guy you 'spoke' to probably knows this due to what gets booked into the workshop. This would be even worse with a hub motor. Spokes fail mainly due to poor wheelbuilding. I asked something similar here: Why am I breaking a ridiculous number of spokes?
I'd go with Spoke Foot, it's got a good assonance to it. Community Bot 1. James James 2 2 gold badges 8 8 silver badges 14 14 bronze badges. Replacing spokes is not quite as trivial as you make it out to be. Welcome to Bicycles SE. We prefer answers on this site to be self-contained.
