Product Info

Equip any bike with a dropper almost instantly: the external routing of the PNW Components Cascade Dropper Post means you can retrofit an older bike, spruce up a spare, or get infinite saddle adjustability without the headaches of fishing cables through your frame. A couple zip ties later, and you're heading up to get down! PNW makes a solid product, and this one's near the top. This V3 of the Cascade features larger diameter stanchions and an extra DU bushing on the 150 and 170mm versions, making them stiffer, lighter and less prone to wobble than the predecessor.
