Are 6 and 7 speed freewheels interchangeable?
If your bike currently uses a 6-speed freewheel, it may be a good candidate for conversion to a 7-speed! The sprockets are closer together on a 7-speed, so the overall width is only a tiny bit wider for a 7-speed vs a normal 6-speed. If your bike has friction shifting , it will definitely work with either 6 or 7.
What is a good single speed gear ratio?
If you’re just starting out on your adventure on a single speed or fixed gear bike, a gear ratio of around 2.7-2.8 will be ideal.
How do you measure a freewheel?
Find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fittings spin with the cogs, it is a cassette system with a freehub. If the tool fittings do not spin with the cogs, it is a threaded freewheel system.
Are all freewheel threads the same?
Freewheel Threading All recent freewheels and threaded hubs, regardless of where made, use ISO threading. The older British and Italian standards use the same thread pitch but a very slightly different thread diameter, and are generally interchangeable.
Are freewheels still used?
A freewheel clutch is now used in many motorcycles with an electric starter motor. It is used as a replacement for the Bendix drive used on most auto starters because it reduces the electrical needs of the starting system.
What sprocket is best for uphill?
The largest sprocket on the rear cassette is usually your steep-climb-bail-out gear. If your largest rear sprocket is 23, 25 or 28 teeth you may find it easier to switch cassettes. A larger 28 or 32 tooth sprocket bottom gear would make things easier on the climbs.
What gear ratio do pro cyclists use?
Pros often use a 55×11-tooth high gear for time trials. On flat or rolling stages they might have 53/39T chainrings with an 11-21T cassette. In moderate mountains they switch to a large cog of 23T or 25T. These days, they’ve joined the big-gear revolution like many recreational riders.
Are all freewheels the same size?
However, because these chains usually have taller thicker side plates, they may not work properly with some cogs smaller than 11T or freewheels smaller than 16T. Freewheels are available in sizes 13T to 28T and in the same two different widths as the cogs (3/32″ and 1/8″).
How many teeth does a freewheel have?
16 teeth
Also – You may notice our flip flop hub on the rear wheel: one cog on each side of the wheel. If you don’t want to count, both are 16 teeth – One is a freewheel cog and one is a fixed cog.

What do the teeth on a freewheel mean?
The number of teeth a freewheel has is pretty important and a little confusing. Basically, the teeth represent your gear ratio, and it’s written like 44:16. The 44 represents the number of teeth you’ve got on your chainring at the front, and the 16 is the number of teeth you’ve got on the back.
What are the dimensions of a 6 speed freewheel?
