Kingpin Suspension
Delivering a smooth ride without the added weight and complexity of a shock and links, Kingpin is our answer for the most demanding gravel riders. Whether you need more comfort to go long, more traction to push beyond or more give to take on the tech - Kingpin is the maintenance-free, lightweight answer to your prayers.
Ride Brilliantly
On every ride, SmartSense has your back. SmartSense’s system of intelligent lights (and optional rear-facing radar) increases your visibility out on the open road and makes it easy to ride smart.
Load Up. Roll Out.
With plentiful gear and waterbottle mounts on the frame and fork, Topstone Carbon is ready to load up and go long.
