Our take on the ultimate all-round gravel bike. Go anywhere, bring everything and then keep on going.
Model Description
This is the pinnacle—the very best of our all-round gravel machines. Buttery-smooth dual suspension lets you float over unpredictable terrain without losing an ounce of speed. KingPin offers up to 30mm of travel in the rear, while the updated Lefty Oliver Carbon fork gives you 40mm up front, keeping things fast, smooth, and suspiciously fun. A mullet drivetrain with new SRAM Force AXS XPLR and an XO Transmission derailleur offers wireless convenience and huge gear range, and Reserve 40|44 GR carbon wheels stay rock steady through every twist and turn. From endless backroads to the toughest race days, this bike sets the bar for speed, control, and all-terrain capability.

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.
Lefty Feels Right
After a decade on the roads, Lefty Oliver still wows with its unique look and gravel-taming performance. 40mm of travel in a stiff, lightweight design boosts confidence and control for faster rides. And with 100-hour service intervals – double that of most forks – it brings low maintenance for more ride time and less down time.
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
Lefty Oliver
Lefty Oliver is our ultralight, single-sided suspension fork for gravel bikes, offering 40mm of travel and incredible steering precision for enhanced control and comfort on any terrain.
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
Topstone Carbon fits tires with a maximum measured width of up to 52mm for the frame and 56mm for the rigid fork. Lefty Oliver's tire clearance is optimized for a 700x47mm tire, with height being the primary limiting factor.
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.
