5-Speed Normandy Freewheel Vintage Touring Bike 14-28 BSC 1.375x24 Eroica RC25

A five-sprocket block threaded BSC 1.375×24 and stepped 14-28 is a practical anchor point for a period touring drivetrain. This Normandy unit is built entirely from steel and shows no oxidation, which keeps the decision simple: you are starting from a clean mechanical base rather than chasing surface corrosion before the first ride.

Drivetrain Logic and Gear Range

The 14-tooth top sprocket gives a usable flat-road and descent ratio, while the 28-tooth low gear opens up loaded climbs and long false flats. With five ratios in between, the jumps stay manageable on rolling terrain — a balance that suits a classic touring bike build or an Eroica-eligible restoration. The BSC 1.375×24 thread is the standard to check against your hub shell before fitting.

Because this is a used component, the photographs are part of the description: tooth wear, plating condition and any cosmetic marks on the body are best read directly from the images. If you are comparing options, the ATOM 66 five-speed freewheel offers a slightly different 14-26 range, while the CYCLO 72 in 14-26 gives another French five-speed alternative for the same era of touring build.
