Can I put a 6 speed cassette on a 7 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.
Are 6 and 7 speed freewheels interchangeable?
If your bike currently has a regular-spaced 6-speed freewheel, you can generally upgrade to 7-speed with little trouble. Since the sprockets are closer together on a 7-speed freewheel, the overall width is only very slightly wider than a regular-spaced 6-speed.
Can I use a 7 speed shifter on a 6 speed cassette?
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.
Can you swap gears on a bike?
The answer is a qualified “yes.” There are different ways to install easier gears on your bike, but it’s not always a matter of swapping just the gears. Depending on the type of components that you already have, and the compatibility of those components, you may need to replace some of other components.
Will a 6 speed derailleur work on a 7 speed?
Six speed is included in there as well, it’s just not common to see. 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 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.
Are 6 and 7 speed chains the same?
Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm.
Can I put an 8 speed cassette on a 7 speed wheel?
It should work. Spacing on Shimano is 5mm for 7 sp and 4.8mm on 8 sp. You’ll wind up with a phantom gear but everything should work.
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 I use 3×7 shifter to a 3×6 bike?
No, the spacing is different. Do you find this helpful?
Can you use a 7 speed chain on an 8 speed bike?
Shimano, SRAM and Campagnolo all use the same chain with 8 speeds. Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm. That is why the reverse is not the case and a 7 speed chain and especially a 6 speed one will not work as well on an 8 speed system. Of others, 9 speed chain can work.
Will indexing work with 6-speed and 7-speed gears?
Also, cog spacing is different from 6- to 7-speed, so no, the indexing won’t work: SP – WRONG! 6 and 7 speed have different spacing, 8 is slightly different to 7 as well.
Can I put 6 gears on a 6-speed transmission?
Your six-speed unit will have 6 indents/positions, and it won’t handle the extra gears. If you have a friction shifter it might work, or it might not. While changing all this stuff you may as well install new cable inner wires and outer tubes too. A cheap set costs about a happy meal.
Is there such a thing as a 6-speed cassette?
If you have 6 speeds it won’t be a cassette. it’ll be a screw on freewheel. Just get another off these off ebay, they’re common enough. Yeah they did Uniglde which is different to Hyperglide. Then they did one that covered both. Then of course there was a 6 speed freewheel.
