Can I put this on a 7-speed bike without modifications? (I'd get new shifters of course)

You can probably get away with it. It will be a little tight, but I'd try it. No promises.

My understanding is you can convert down but not up. Here's what I mean, 10 speed cassette can be converted down to 9 or 8 possibly 7 and all you would need is a space for the freehub. Explanation:The freehub gets shorter in lenth to allow for bigger gears. So to put a 8 speed on your bike you would need to change your freehub. Are you converting bike to 8 speed? Or are you just keeping seven speed shifter and deraillier. If so just buy 7 speed cassette geared for the way you ride, it would keep things simple.

Wheel hubs, where you attach these, are generally made in two sizes: for 7 cogs or less, or for 8 and up. It probably won't fit. See Sheldon Brown's site for more than you ever wanted to know about bikes.

If there is a spacer on your cassette, meaning it takes up the room that an additional gear would take, then simply take that off and you can fit 8 speeds, if not, you'd be better off buying a new wheel. do bear in mind that the more you spend on a wheel, the less your going to need to true/maintain it!

I assume you mean your shifters only have 7 positions. With an 8 cog cassette you would set the the limits of the shifters to leave out either the smallest or biggest cog, i.e. you will be able to shift to 7 of the 8 cogs. But, you would be better off just using a 7 speed cassette.

If you have Tourney shifters with a 7 speeds rear derailer and 3 speed front derailer you should be fine. The most difficult part is fine tuning the cable length nuts to get the shifters just right.

Little late to the party, but SRAM 4.0 rear derailleur is 1:1, so these shifters are compatible.

If your going to just swap out the gear hub, you will need new spokes and have some one lace the new hub into the original rim , then just change the selector and everything should bolt onto your frame, I converted my 24 speed mountain bike to the 8 speed gear hub and enjoy it , I never changed gears on the front chain rings so no loss to me, I like simplicity

probably not.I used this handlebar on a Trek 7.4 FX. It had Shimano Acera brake levers and shifters.You could probably use most shifters and brake levers that are found on bikes with straight handlebars.I don't think typical road bike brake levers would work with this handlebar.

Are you upgrading to 8spd? If so, you will likely need to replace the chain, deraileur, and shifters to accommodate the extra gear.

It will, but not as well as you think. A 6 speed freewheel has a larger cog distance from the next one, and a 7 speed freewheel/cassette is much closer. However, there are alternatives you can buy (Shimano Revo Shift 6 speed or SRAM MRX Comp 6 speed) that will match performance well. Also, when you get the indexing and limits correct, give the shift cable a good stretch, then readjust the indexing if necessary. This stretches the cable before leading to future shifting problems. As for the front, it will work perfectly.

Possibly. If your shifter has a "friction" mode, it will work with a 6 speed freewheel. In order to answer in more detail, we would need to know the brand, as suntour and shimano had different amounts of pull.

Yes, there are bolts on both sides that are used to secure the Shifter assembly. So it could be switched.D

Shimano 105 or Ultegra derailleurs also seem to be of good quality and should work fine with those shifters.

Should be no problem, since they are simple friction shifters with no stops. Both shifters are basically exactly the same. I am currently using them on a 7 speed rear, changed from a 5 with no issues.

As long as they are both 8 speed. So if you have a 8 speed cassette and and 8 speed derailuer than a sram 8 speed shifter will work.

Quite certain the answer is Yes. 7 speed twist with a 7 speed derailleur. Etc, Etc.

The bike I used them on was a 21-speed(3x7) Schwinn(from WalMart) and they worked great. Unless there is something unusual about the Mt. Fury frame geometry, these shifters should work. Hope that helps.

Freewheel/Sprocket assemblies are generally "mated" to derailleurs and shifters; hence a 7 sprocket freewheel will generally waste two sprockets mated with derailleur/gearing that was designed for 5 sprockets. It will probably still be operable; however, in addition to the wasted sprockets the change in alignment due to different sprocket spacing will mean awkward shifting (at least for indexed shifters) and probably noisier operation.

yes .you can even use index shifting if you like ----shimano spacing is the same for 6/7/8gears drives cassette or frewheel....... happy rides.
