Nothing is impractical with Topstone Carbon 4
The best gravel bike for everything from dirt roads to singletrack trails. With the grip and comfort of Kingpin suspension, nothing is off-limits. With plenty of bottle mounts and frame and fork mounts, the Topstone Carbon is ready to load up and travel the distance. Enter the most treacherous corners with confidence and exit smiling: thanks to the OutFront geometry, Topstone Carbon is stable on rough surfaces while remaining agile and easy to ride in other situations.
Kingpin suspension
Increased comfort without the added weight and complexity of joints and shock absorbers: Kingpin is the answer to the most demanding gravel users. Whether you need more comfort for long rides, more traction for extreme cornering, or more absorption for more technical trails - the Kingpin is the lightweight, maintenance-free answer to your prayers.
Engineered simplicity
Low-friction bushings on the Kingpin suspension thru-axle ensure smooth operation, maintenance-free reliability and a savings of over 100g compared to traditional bearings.
Tire size and compatibility
The new design with lowered chainstays allows you to use tires up to 700x45mm or 27.5x2.1", leaving 6mm of wheel clearance on both sides and with standard camber for easier wheel changes.
Specific for each user
The Proportional Response construction, specific for each size, gives optimal rigidity to each frame size, so as to offer everyone the superb driving feeling for which the Synapse is known.
