Highlights

- Cannondale Wheel Sensor delivers hyper-accurate speed, distance and route info, service reminders, and more via the Cannondale App.
- 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 inpidually 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.
*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*
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.
