Go ahead and ride the shock open it'll still claw up anything without sacrificing on big hits and deep rollovers.The key difference between Switch Infinity and the Switch Link design it replaced is that the older model exhibits a momentary harshness when rapidly successive hits kept it hovering above the 30% stroke point. To address this, Switch Infinity replaces the Link's sinuous travel arc with a linear plane of motion, so the eccentric link changes di...
