Sapim CX-Ray Straight Pull Spokes
|Availability:||In stock (106)|
The CX-Ray is Sapim's flagship high performance spoke. Don't let the low weight of these spokes fool you; the CX Ray's tested tensile strength is nearly 50% better than a standard straight gauge spoke, with a fatigue life three times as long! These spokes hold their own under the world's best athletes; road racers, triathletes, and even downhill racers. Consequently, the CX-Ray is the go-to spoke for any high end wheelset, from low spoke count sub-800 gram climbing wheels to ultra-durable, high-strength 32 spoke mountain wheels. These are the lightest and most durable stainless steel spokes available today.
Straight Pull CX-Ray spokes are intended for use on hubs with straight pull flanges, such as those from Extralite.
Please note that Sapim spokes typically measure slightly shorter than the listed length (.5-1mm). These spokes are sold individually and do not include nipples.
Please take extra care with your calculations and measurements as Straight Pull spokes are less forgiving in the build process of minor length errors.
We recommend that high end wheels built with CX-Ray spokes be assembled by an experienced wheelbuilder. We are happy to provide this service, and can provide helpful suggestions in hub and rim selections. Please contact us directly or submit a custom wheel build request here.
While these spokes do not require any special wheel building techniques, the thin bladed section must be supported near the nipple to prevent helical twisting. The best tool for this purpose is the Sapim Bladed Spoke Holder. With a 2.3 mm wide blade, the CX Ray does not require slotting of the hub's spoke holes.
