Cannondale Topstone Alloy Sora 2020 Gravel Bike Mantis Information

Season : 2020

Brand : Cannondale

Code : C15800M10

The Cannondale Topstone Sora is the perfect starting point for anyone wanting to explore and ride the routes less travelled. 

The SmartForm C2 Alloy frame has clearance for up to 42mm wide tyres and is light and durable, improving comfort and control whether your exploring gravel country roads or rough, potholed roads. Combined with the frame geometry, slack head angle and long 55mm fork rake this bike delivers the right balance for endurance rides and stability for any speed. 
Pair all of that with the full carbon fork to improve your overall comfort for any distance and the 12mm thru axle with tapered steerer allows for responsive, nimble steering for reliable handling in any condition. 
The Promax Decoder R mechanical disc brakes will give you confidence to race down steep descents and sharp corners knowing you have stopping power in all conditions, allowing you to ride all year round. The Shimano Sora 2x9 gear transmission will help you fly up long climbs, with the wide range of reliable gears available to you.
