Rondo BOOZ ST Steel Belt Drive Bike
Take on the city streets on the Rondo BOOZ ST Steel Belt Drive Bike. Sporty and fast, this bike rolls on 47c 650b tyres that soak up the impacts of potholes and other irregularities, and get you hopping on and off pavements with ease. They may be fat, but these tyres still roll fast. Wide flat bars ensure excellent control over your steering.
The single speed carbon belt drivetrain runs smoothly and simplifies maintenance, and hydraulic disc brakes ensure you can stop fast, as and when required, even when the roads are wet. Mudguard mounts mean you can reach your destination dry, making this the perfect commuter.
Features
- Adjustable head angle and fork trail
- Belt Gates carbon drive
- Hydraulic flat mount disc brakes
- Mudguard mounts
- Up to 700 x 32C and 650B x 47C tyre clearance
