MATERIAL: Alloy 7075 WEIGHT: 1636g (wheels only) HEIGHT: 30mm DRILLING: Front/20 Rear/28 HUBS: Sealed Alloy 7075 SPOKES: Alloy 3mm Bladed A performance driven design, our S-300 wheels were accomplished with the help of every day cyclist like you. We are glad to introduce our first rim design with a light rim extrusion that makes it even more responsive. We laced them up with machined axle bolts which secure it tightly. The washers are made of brass and have deeply knurled contact faces. This ensures they’ll grip onto the dropout face without damaging the frame. Simple, strong and stiff our Elite riders put them to the test conquering mountains and riding through the must rugged streets. They speak for themselves.
