Product Details

Genesis Day One 20 2018 Commuter Road Bike

The Day One combines the one cog/one chainring aesthetic of a singlespeed with the knee-sparing common sense of Shimano Nexus 8-speed hub gearing.

Shimano Nexus 8-speed hub gear

  • The gear mechanism is enclosed in the rear hub, shielded from the elements.
  • The benefit of this system is low maintenance reliability.
  • The fact that the chain doesn't spend its life being derailed between cogs means that it lasts longer.
  • The 8-speed Nexus hub's gear range is equivalent to an 11-38 cassette.
  • The gearing is low enough for steep hills, high enough to accelerate on the flat.
  • Another benefit of Nexus is that you can change gear when the bike is stationary. Just like you can in a car.
  • This is very useful if you have to stop at the bottom of a hill. No need to pedal off in too high a gear.
  • The gears are operated by a single conveniently-located Microshift bar-end shifter that takes up no bar space.

Same as the Genesis Day One 10

  • The Mjölnir seamless, double-butted, cold-drawn chromoly frameset delivers the lively feel we've come to expect from good quality steel.
  • CST Sensamo Speed 700x35c tyres combine speed potential, cobble cushioning comfort and the extra safety of reflective sidewalls.
  • Genesis compact bars, sized by bike size, offer easier transition from the bar tops to the drops.
  • ProMax disc brakes bring a new level of all-weather low maintenance stopping power to singlespeeds.

'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.'
