Can I use a 7 speed derailleur on a 6 speed cassette?

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.

Can I use an 8 speed derailleur on a 6 speed cassette?

Easy answer. No, this won’t work with 8 speed indexed shifters. The reason is that one click on your shifter doesn’t move your derailleur enough to shift to the next cog on your 6 speed cassette. Explanation If we check a table of cable pulls, we see that a 6 speed Shimano cassette has a pitch of 5.5mm.

Can you replace a 6 speed freewheel with a 7 speed?

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 9 speed derailleur on a 6 speed cassette?

Up through 9-speeds, all cassettes use very nearly the same width of sprocket teeth, and will work with 7/8 or 9-speed chains. Old Uniglide 6-speed cassettes have larger spacing between sprockets, and like older freewheels, have the same shifting issues.

Can I use an 8 speed derailleur on a 7 speed cassette?

8 speed shifter and cassette, 7 speed derailleur? You’ll be fine. There’s no “probably” about it. 6-, 7- and 8-speed gear is all cross-compatible in terms of chain width.

Can I use a 7 speed chain on an 8 speed cassette?

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.

Is 7 gears enough on a bike?

In terms of how the number of gears affects the overall ride of the bike, a 21-speed is generally faster with smoother transitions and pedaling. The 7-speed is adequate for most riders, which is why many people choose the slower option.

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 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.

Will an 8 speed derailleur work on a 7 speed cassette?

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.
