So we’ve combined these ratios along with a zero-offset seatpost to make spinning easier."The new Ridley Jane SL is the flagship bike in the new women’s range and it’s an out-and-out performance bike (it’s the female equivalent of the Noah SL aero bike).
This led to the engineering team researching what women need from a specific bike design.
This began to turn around in the camera and electronics industries in the 1950s, but Japanese companies didn't figure out how to make and sell bicycles for the U. This was a 10-speed, pretty much all steel except for the handlebar stem and the Dia Compe brakes.The Jane SL has the same aero-properties as the Noah SL and the geometry matches too, it's just available in much smaller sizes.The component changes include stems between 80-100mm across the size range, bars between 38/40/42, a wider saddle and crank lengths of 162.5mm and 165mm are offered too.Classic style with machined cut-outs (42t has drilled lightening holes).Minimal lead chamfer and full height teeth with no cut-outs or 'shift pins' give perfect engagement with the chain.
