How do I calculate spoke length?
Pull both spoke heads inward towards the center to seat the nipples. Using the narrow tips of the caliper jaws, measure from inside to inside of each J-bend. Record this measurement to the nearest tenth of a millimeter. In our example, each spoke measured 266 mm, with the J-bend-to-J-bend at 35.7 mm.
Do I round up or down for spoke length?
I’d round down if they are butted spokes because they can stretch. Just a little bit, but enough. I prefer to have enough length to get the spoke flush with the inside of the spoke head, but I’ve also ran out of threads on a spoke before. If you run out of threads, you can’t tighten it any more, and you’re just stuck.
How do you measure hub spoke length?
Divide overall hub width by two to find the center of the hub. Now, measure from the middle of the right flange to the face of the right side locknut. Use a straight edge against the lock nut or axle end cap to make it easier — this simply extends the line of the face outward.
Are CX Ray spokes worth it?
Or rather, the question really is whether CX-Rays are worth the extra money. The answer we’ve always provided is that the spokes are the same weight but CX-Rays are purported to have some aerodynamic advantage. If you’re looking for “every last watt of speed,” they’re the way to go.
What are CX Ray spokes?

Are drive side or non drive side spokes longer?
Yes, the rear drive side will be the shorter spokes. If you are using the same rim AND hub, you should be in good shape. If you changed rims, your spoke lengths may be off for your current build.
Should I round up or down for spoke length?
Spoke length calculators output lengths to the tenth of a millimetre, which must be rounded to match available supply.
