A root or a rock at speed usually means one thing: check your line, or take the hit. On a 32-inch wheel, that same obstacle sits at a shallower angle, and the wheel rolls over it instead of catching on it. That’s the starting point for the Yarrow SL32 Ninefold: built for XC and marathon riders on set routes and mountain terrain, around the largest wheel size we make.
The rim is 25mm deep and 32mm internal, wider than the 30mm many other brands still build around. That extra width isn’t free — the rim carries a little more weight for it — but it supports a modern, wide MTB tire properly at the lower pressures that give you grip on loose, technical climbs. 30mm isn’t a bad width, it’s just a step behind where tires have moved.
At the hub, Onda-M is our own design, made in Europe: Center Lock, Boost spacing (front 15×110 / rear 12×148), and a hub set that weighs just 265g for the pair. Building our own hub means we can match it exactly to the spokes we want to run: 28 Sapim RC-1 PBO fiber spokes front and rear. We’ve worked with several synthetic rope-style spoke technologies over the years, and each comes with its own trade-offs. RC-1 gives us the comfort and low weight without the downsides we’ve seen elsewhere: it doesn’t stretch, doesn’t discolor, and doesn’t fray.
9th Wave started in mountain biking, and that background shapes this wheel. Weight matters, and we don’t pretend otherwise, but not at the cost of strength and comfort. The goal isn’t to build the single lightest wheel possible — it’s to build one of the lightest in the world, without giving up the wide rim and the damping spokes that make it work on the trail. The ART asymmetric rim design keeps spoke tension even side to side, for a wheel that holds its line under the extra leverage a bigger wheel puts through it.
This is a wheelset for set routes, mountain climbs and flow trails — not for downhill. Hand built in the Netherlands with rim tape and valves installed, and once you register your wheels, the carbon rims are covered for life. At 1235g for the set, it climbs as readily as it rolls over what’s in front of it. If you ride 29-inch wheels instead, the Yarrow SL29 Ninefold uses the same build.
