Can I replace a 6 speed cassette with a 7 speed?
SP – WRONG! 6 and 7 speed have different spacing, 8 is slightly different to 7 as well. If the bike is from post 1989 or so it will have a block not a cassette, and a cassette won’t go on the hub. If it’s a 6 speed cassette it may have a threaded top cog meaning a modern 7 speed cassette won’t fit either.

Are 6 and 7-speed chains the same?
Shimano, SRAM and Campagnolo all use the same chain with 8 speeds. The chain for 7 speeds is a bit wider – 7.3 mm, while a 6-speed one is substantially wider – 7.8 mm.

Why is a cassette better than freewheel?
A cassette is the modern alternative and has quickly overtaken the freewheel. Cassettes have a series of straight splines that form the mechanical connection between the sprockets and the cassette-compatible hub, which is called a freehub and contains the ratcheting mechanism.
Why are some Freehubs loud?
Loudness in the freehub/freebody is usually due to the very light oil used to lubricate the inner parts. Thicker oil can be used to lessen the noise and even grease in some cases, but it’s high viscosity is pointed at for not being so efficient.

Can I convert freewheel to cassette?
Cassette hubs cannot accept freewheels; nor can freewheel hubs accept a cassette. The freehub body of a cassette hub is shaped specifically for a cassette. Meanwhile, freewheels and freewheel hubs operate with a threaded system. Thus, it’s impossible to mount a freewheel on a cassette hub.
