Topstone Carbon distills our experience making fast race bikes, comfortable endurance bikes and ultra-light dual suspension mountain bikes into the most off-road capable, and on-road comfortable, road bike ever made. Designed for maximum fun in places most gravel bikes would fear to tread, or maximum comfort in more sedate terrain.
Revolutionary, super-light suspension that lets you ride harder on dirt and more smoothly on pavement. Better control. Better traction. Better comfort. Nothing sacrificed.
Up to 30mm of suspension, without the weight and complexity of a shock or linkages. A special thru-axle pivot in the seat tube allows engineered flex zones in the rear triangle and top tube to do their magic, absorbing bumps and vibration and improving comfort, traction and control whether you're seated or standing.
EVERY RIDER IS DIFFERENT
PROPORTIONAL RESPONSE CONSTRUCTION
Suspension and overall frame ride-feel is custom tuned by size. We manipulate the carbon layup and tube dimensions to deliver the right amount of flex and stiffness for the rider’s size, so all you need to do is get on and ride.
THE LAST DETAIL
We thought of everything. Big clearance for big tires. Tons of gear and storage mounts. Speed Release thru-axles. DirectLine cable routing. Internal dropper post compatibility. In short, the works.
