Cannondale Topstone Neo Carbon 2 Disc Electric Gravel Road Bike 2021
The Cannondale Topstone Neo Carbon 2 Disc Electric Gravel Road Bike is a sleek and accomplished machine that doesn't shy away from rougher terrain. With a lightweight Cannondale BallisTec Carbon frame and handy removable downtube battery, this is a bike designed with versatility in mind. The removable Bosch Performance Line CX battery offers an additional 250W to aid your commute or longer off-road explorations, so you can go further without compromising comfort. KingPin Suspension ensures smooth riding regardless of surface, so you can be confident in the Topstone's unfaltering capability. Expert geometry and a carefully crafted rider position blend to create the Dialed Endurance Fit; low enough to avoid compromising speed, but upright enough to enable control when taking on tougher off-road routes.
The 11-speed Shimano 105 cassette is coupled with a 46/30T chainring, ensuring you won't be short of gearing options if you opt for challenging terrain. Additionally, GRX components boast resilience and gravel-specific ergonomics for an optimised riding experience. Lightweight KOM rims are tubeless-ready, delivering WTB's easiest to mount tubeless system yet. These are paired with WTB Riddler TCS Light tyres, reliable for speed and traction round those tighter corners.
Highlights
- Shimano GRX groupset and 105 11-speed cassette
- BOSCH Kiox on-board bike computer with colour display and wireless Bluetooth connectivity
- Fully mudguard ready. A removable mudguard bridge on the rear stays is there when you need it, gone when you don't
- Speed Release Equipped. Speed Release thru-axles offer the stiffness and solid feel of a thru-axle, with the easy use of a quick-release axle
- Easy Internal Cable Routing. With Cannondale's DirectLine cable routing, an internal tube guides the cable and housing through the frame, from entry to exit for headache-free service
- An integrated wheel sensor delivers hyper-accurate speed, route and distance info, registers your bike, reminds you of needed services and more, all through the free Cannondale App
- Topstone Carbon comes with 700 x 37c tyres for great road speed and gravel grip
- LockR Pivot. Kingpin's LockR thru-axle pivot locks the left and right seat stays together, preventing independent rotation for a solid feel and instantaneous response
