Cannondale Topstone Carbon 2 GRX 2025 Bike (Obsidian)

KingPin Suspension

Cannondale's 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.

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.

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.

Tidy does it

Internal cable routing throughout the frame, combined with Conceal Stem, delivers a tidy, integrated look.
