The Shimano Front Freewheel (FFS) was a proprietary bicycle drivetrain design of the 1970s that placed a freewheel between the pedal cranks and the front chainrings – enabling the rider to shift gears while coasting. [2] FFS rear freewheel is different than a standard freewheel because it's "stiff" with more friction than a normal rear freewheel.
The London Freewheel was the brainchild of David Love, vice-chair of London Cycling Campaign, inspired by riding in the Cape Argus Cycle Race in 2001.[2] TFL promoted it with the goal of giving more people a chance to discover cycling as both fun and efficient.[1]
The individual sprockets on a Hyperglide cassette or freewheel are designed specifically to work with their neighbours. [3] For example, the 18-tooth sprocket on a wide-range cassette (such as one for a mountain bike) will have a different ramp pattern than the 18-tooth sprocket on a narrow-range cassette, because the number of teeth on the neighbouring sprocket requires a different ramp ...
A freewheel was also used in the original Land Rover vehicle from 1948 to 1951. The freewheel controlled drive from the gearbox to the front axle, which disengaged on the overrun. This allowed the vehicle to have a permanent 4 wheel drive system by avoiding 'wind-up' forces in the transmission. This system worked, but produced unpredictable ...
Multiple speed freewheels were common on quality high end bikes until the late 1980s. [3] Suntour — Maeda Industries (Japan) introduced a compact 6 speed freewheel which reduced the spacing between the sprockets and was the same width as a standard 5 speed freewheel but required a narrower chain than the standard.
If used with a screw-on freewheel, a special hub with a left hand thread for a special freewheel must be used, which is also threaded left hand and ratchets the opposite direction of a normal freewheel. If the freewheel and hub were threaded with right hand threads, the torque applied by pedaling would loosen and unthread the freewheel from the ...
