ATOM 77 5-Speed Freewheel 14-28 Vintage Eroica Bike 34.7x100 RC11

A Direct 14-28 Range for Five-Speed Drivetrains

The ATOM 77 freewheel carries a 14-tooth smallest cog and a 28-tooth largest, giving the rider a useful spread for rolling roads. Five speeds and a steel body keep the unit in line with original equipment from the period. No oxidation is present on this example.

What the Five-Speed ATOM 77 Provides

Each of the five sprockets is machined for engagement with a standard chain. The 14-28 progression was a common choice for riders who needed a low gear without sacrificing top-end pace. This freewheel is identified as a five-speed (5 V), making it suitable for classic drivetrains.

For comparison, a Maillard 14-26 5-Speed Freewheel from 1977 offers a slightly narrower range. If your build calls for a taller top gear, the 1980 MAILLARD SUPER 700 13-28 is another period option.
