Can you put a 7 speed cassette on a 6 speed hub?
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.
Can you replace a 6 speed freewheel with 7 speed?
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.
Can I replace a 6 speed cassette with an 8 speed cassette?
You would need to verify frame dropout spacing, add axle spacer to the drive side and re-dish the wheel to re-center. Alternative is to build a new wheel with a cassette hub (possibly re-use the rim and spokes). You probably do not need a new derailleur for 8-speed conversion but a narrower chain would be advisable.
Can you put a 7 speed shifter on a 6 speed bike?
You would need to either add a 7 speed cassette or use 7 speed spacers on the current 6 speed cassette. Are you sure it’s a cassette? Many 6 speeds are freewheel. The derailleur should work fine.
Will a 7 speed shifter work on a 6 speed bike?
Re: Can you use a 7 speed shifter on a 6 speed cassette? The “numbers” say they don’t match. The cable pull of a 7 speed is less than a 6 speed so, though a couple of cogs might work, the rest will gradually not. You’ll never know if you don’t try it.
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.
Are 7 and 8 speed cassettes interchangeable?
A seven speed cassette will fit on an 8 speed freehub with the use of a spacer.
Will a 7 speed derailleur work on a 6 speed?
So yes, a six speed rear derailleur will work correctly with 7, 8 or 9 rear speed systems. The derailleurs in these speed groups will all move the same amount based on the amount of cable pulled by the shifter.
Can you use a 7 speed derailleur on a 6 speed bike?
you’re trying to take that 7 speed cassette and try to use it on the hub that 6 speed freewheel came off of…not saying that, but that was my first thought when I read it… hell, it’s late. No, what I am thinking of doing is taking the derailleurs off a 6 speed bike and putting them on a 7 speed bike.
