Genesis Day One 20 2019 - Road Bike
The Day One 20 Brings All The Associated Benefits Of Singlespeed Riding With It's Single, Ultra-efficient Optimised Chainline And Adds The Practicality Of Shimano's Nexus 8 Speed Internal Geared Hub With Its' Wide-range Gearing And Sealed-from-the-elements Drivetrain.
Returning a similar range to a conventional double setup (30-92 gear inches, with a whole lot of useable range in between) and with mounts for racks both front and rear, the Day One 20 is the ideal low-maintenance workhorse for those wanting to perhaps carry moderate loads efficiently and comfortably over undulating landscapes. It's a supremely versatile bike - we've even seen them geared down (via a simple and affordable sprocket change out back) and handle some pretty demanding expeditions with aplomb.
Occasionally, without notice, manufacturers change product design and/or specifications.
