Smiles for Miles
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.
FEATURES
KingPin
Our innovative gravel rear suspension is light, simple, and effective. A thru-axle pivot in the seat tube allows the rear triangle and seatpost of the bike to flex vertically, delivering up to 30mm of bump-smoothing travel.
StashPort + StashBag
StashPort is our take on a downtube storage system, accessed beneath the water bottle cage. Every bike includes StashBag, a specially designed bag for your essentials.
Tire Clearance
Lots of room for modern gravel rubber. The frame clears tires up to 52mm wide with a single ring setup, or 45mm for a 2x, while the fork fits up to a whopping 56mm wide tire. Measured size, of course.
Dropper Ready
Built to accept an internally-routed 27.2mm dropper seatpost, which shouldn´t be a surprise on a bike this capable.
Proportional Response
Tuned for the rider, our size-specific construction creates optimal stiffness and compliance for each frame size. So, every rider benefits from the ideal ride feel and comfort of KingPin.
Outfront Steering Geometry
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.
Tidy Does It
Internal cable routing throughout the frame, combined with Conceal Stem, delivers a tidy, integrated look.
