650 Adventure



Built to accept 650x42B tyres with clearance for mudguards, the 650 Adventure is a true all-roads tourer and ‘gravel-basher’. Fitted with 37mm or wider tyres, the bike can be ridden at speed on unmade roads even when laden. Stripped of luggage and mudguards, it makes a superb gravel bike with the performance envelope of a fully-rigid mountain bike on semi-slicks.

It can be built for either derailleur or hub gearing such as Shimano's Alfine hub gear or the Rohloff 14-speed hub. It also 
makes possible the fitting of tyres 
and superior cornering and braking lower rolling resistance especially when laden  suitable for off-road riding such as Continental’s Tour Ride, which turns the machine into a fully-rigid mountain bike and the ultimate go-anywhere adventure cycle.

Riding wider 650B tyres:

Whether touring with panniers, tackling a gravel cyclo-sportive, commuting or even riding long-distance sportives such as the 225-mile Rapha Manchester-London event, the rider enjoys enhanced ride 
comfort and superior cornering and braking grip. Tubeless-compatible 650B tyres such as Panaracer's Gravel King and Schwalbe's G-One Speed also provide reassuring puncture resistance in all conditions. 

'The ride is surprisingly luxurious and the handling very assured. I continue to be surprised by how nimble and fast it is.' - Hugh P

'Utterly stable and predictable at speed and on bumps. Much better than most "sports" bikes' - Mark B
