Alternative to the norm
Calling all skeptics: electronic shifting is the real deal
Clean and ergonomic design
Real luxury items
Simple, effective shifters
Designed primarily for running on single-speed bikes with vertical drop-outs (not fixed or those with coaster brakes, though), my Singleator has been in use for many hundreds of miles on my Airnimal Chameleon folder that I converted to hub gears.
Shimano's SL440s have been the only dedicated flat barred road shifters on the market to date. Now Campag have their own; the Ergopower FBs from the Veloce grouppo, for those who favour the Italian way but prefer the comfort of a flat barred set-up.
