Pay with Cycle to Work

We accept Cyclescheme, Gogeta and Green Commute Initiative.

Buy this part (and fitting) through Cycle to Work: Cyclescheme, Gogeta or Green Commute Initiative. No bike needed. Subject to your employer's scheme.

  1. Ask us for a written quote showing the exact items and price.
  2. Apply through your employer's provider (Cyclescheme, Gogeta or GCI) using our quote. Your employer approves it.
  3. Collect from our workshop at Unit 1, The Swan Centre, Rosemary Road, London SW17 0AR. Bring your certificate or voucher code.

Savings depend on your tax band and your employer's scheme. Cyclescheme and Gogeta say you can save up to 47%; GCI says 28% to 47%.

Cyclescheme and GCI exclude cameras and GPS bike computers.

  • Digital Integrated Intelligence or Di2: with programmed automatic motion at the touch of a switch the Dura-Ace Di2 rear derailleur is quick, smooth and effortless, making for unmatched drivetrain efficiency
  • The rear derailleur is now the brains of the system with wireless connectivity to the shifters. It acts as the point the system is charged, provides ANT+ connection to 3rd party devises and replaces the handlebar junction
  • Button on the derailleur for Di2 operations, and LED light denotes synchronized shift mode, setting mode and charge requirements
  • Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift
  • Synchronized Shift designed, developed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur
  • The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching
  • Low profile Shadow derailleur design
  • Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
  • 11-34T wide gear ratio capacity will cater for compact setups as well as the traditional road double
  • Full carbon fibre inner and outer pulley plates enhance rigidity and reduce weight
  • Titanium B axle bolt for further weight savings
  • High tolerance cold forged aluminium link plates and body construction is extremely light and durable
  • Four self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting
  • Pulleys are made of tough DuPont Zytel for longer life and less chain noise
  • 12-speed E-tube Di2 compatible
