New Spinergy Carbon Fiber 29er Wheel At Sea Otter

Spinergy was showing off a new prototype carbon 29er wheelset at Sea Otter. I took a few pictures and our man Byron shot a short demo video of the wheels in the Mtbr booth (below). The 24-spoke disc brake-compatible wheelset has 20mm rims, uses a Hadley freehub on the rear and is SRAM XX1-ready. The new wheels weigh in at less than 1400 grams – that’s over 400 grams (about a pound) lighter than Spinergy’s aluminum 29-inch disc brake wheelset and very competitive with other available 29-inch carbon fiber wheelsets. Apparently it’s not a prototype anymore, either. I just got off the phone with one of the Spinergy reps and he said the new wheels will be officially introduced this fall at Interbike and will be named the Xyclone Full-Carbon 29er wheelset.

Carbon fiber isn’t the only tricky bit on Spinergy’s new carbon wheels. All of Spinergy’s wheels are built around their PBO spoke technology. The spokes are made from polyphenylene bensobisoxazole fibers. Every spoke has over 30,000 strands of those fibers encased in a waterproof, UV-proof, chemical-resistant composite. Spinergy says their PBO spokes are about half the weight of steel spokes and three times stronger. The PBO spokes are available in a bunch of colors and they even have aero spokes made by compressing and flattening them.

When I ran into the Spinergy guys at Sea Otter, they were showing off the new carbon fiber 29er wheelset on a 19.92-pound Scott Spark 900 full-suspension bike that had just been ridden in the pro short track XC race. That’s a race-ready 19.92-pound bike, not a pedal-less photo shoot bike. It was built up with a DT Swiss carbon fork, SRAM XX1 drivetrain, Formula R1 disc brakes, Crank Brothers Eggbeater pedals and 4 ounces of Stan’s sealant in each tire.

    Are they ust tubless, tubeless ready, or gheto tubless? Is the rim bed sealed? What is the internal width? How much do replacement spokes cost and can you replace spokes at home? Oh, and are they making a center-lock version? And what axle types are available? Converable endcaps?
