Kingpin is our lightweight, go-for-longer rear suspension. Maintenance-free and complexity-free, it gives the Topstone frame legit rear-wheel travel without compromising stiffness for the sprint. Kingpin provides a smoother ride, more traction to push harder, and more give to take on the rough stuff. You’ll hardly know it’s there, but you’ll be very glad you’ve got it.
Bring It All
Our all-new StashPort storage system in the downtube is designed to be concealed yet convenient. Paired with the special StashBag, you can bring your essentials along for the ride and know that they’ll be kept safe, whatever you get up to out there. Meanwhile, multiple mounting points on the frame, mean more gear and more adventures.
Tuned Ride
A dialed-in ride, just for you. AKA: Proportional Response Construction. Everything from the carbon layup to the geometry on Topstone is individually tuned by frame size. So that the bike – including KingPin suspension – works in harmony to give you the best ride for you and your dimensions.
