Perfectly integrated with the KHS SixFifty 680+
The Magnum brings the adjustable, bottomless feel of the Mattoc Pro 2 to a wider 110x15mm axle platform. Featuring hydraulic bottom out adjustment, IVA air volume system, and separate high and low speed compression damping circuits, the Magnum provides DH performance in a trail oriented package.
These rims are perfectly integrated with the KHS SixFifty 680+
There’s a reason we named this wheel after a bad-ass pig – Mulefüt pigs have uncloven hooves similar to a mule. Sort of like this fat bike rim that’s steadfast, durable and able to ramble over anything. The Mulefüt rim is wide enough to handle a big-ass tire and a sizeable tire patch. And, it has strategic cutouts to reduce overall weight.
