PRODUCT HIGHLIGHTS
Delivering a smooth ride without the added weight and complexity of a shock and links, Kingpin is our answer. Whether you need more comfort to go long, more traction to push beyond or more give to take on the tech.
Confident stability meets nimble agility. An extra long fork offset paired with a slack head angle keeps the steering light and lively, yet delivers unreal confidence at speed and in the rough stuff.
Built to accept an internally-routed 27.2mm dropper seatpost, which shouldn't really be a surprise on a bike this off-road capable..
Load Up. Roll Out - With plentiful gear and water bottle mounts on the frame and fork, Topstone carbon is lighter, faster and ready to load up and go long.
