anyway this will work on 7-speed until I upgrade to 8-speed?

I would think this should work on 7-speed. You just don't trigger it to the 8th gear.
1658880
Yes. A 7-speed & 8-speed have the exact same amount of spacing between sprockets. The only thing is that one of the gears on your shifter won't be used for anything. If it were the other way around, then you would not be able to shift to one of your eight gears with a 7 speed shifter.

Yes, it will work fine. You'll have one gear shift click that won't do anything for now. The rear derailleur cable adjustment and the high and low limit screws on the rear derailleur will determine whether your "dead" click is either a high gear or a low gear. It will work fine for a 7 gear Shimano based rear sprocket.

I used a 7 speed cassette on mine. I had to adjust the spacing on the axle. I took the old axle spacers from my old rim and transferred them over.

Yes it will work. If you change to a 9 or 10 speed you would need derailleur.

Yes as long as you use a 7 speed shimano gear selector and your bike has a freewheel hub.

Hello, We are only able to order the 3 speed wheel kit from the vendor, they do not carry a 8 speed wheel kit.

Yes it will. The pull ratio is not 1:1-- this has the same ratio as all older Shimano ders. The only problem you might have is if you run a slightly wider chain through it. I don't think it will jam up or anything crazy like that, but you might get a little rubbing on the cage as the chain deflection increases (i.e. while you're cross chained). Just run a 9-speed chain and you'll be completely okay. Again, not that the 8-speed chain is going to lead to a catastrophe. Shimano did change their pull ratio when they moved their mountain drive trains to 10-speed. This is a little annoying, but at least there are more modern 9-speed options available (10-speed road ders will still work on lower-speed mountain drivetrains, though. I'm running a 10-speed 105 der on a 7 speed drive train with an indexed shifter :) ).

Yes. I am currently using a 7 speed cassette on this hub. However you will need a spacer as the width of the 7 speed cassette is not the same as the 8 speed cassette.

This is designed for a 9-speed chain, but should work with a 7-speed drivetrain as well.

I'm using the barend shifters with my old 8 speed alivio rear and front derailleurs with 9 speed cassette, there won't be any issue if you are going to use 9-speed all the way, cassette, rear and front Derailleurs

I used 8 speed cassette, I did not install 7 speed cassette, I know it will fit, sorry I do not know too much about cassette, I am familiar with cluster for over 40 years.

I would think so. As long as the derailleur supports at least as many speeds as you have.
1826403
Yes as long as your gear count is the same. For example, if you have a 9-speed shifter and cassette you need a 9-speed derailleur. Same with 10-speed. If these match you are fine mixinh 771 and 772 component sets.

Since the bar end shifters are intended for 8-speed rear cassette you will need to find a compatable derailleur. I checked online and most everything is 9-10-or11 speed now. In the past I have had both Dura-Ace and Ultegra derailleurs by Shimano that worked great but they were 8-speed systems ant that was about 15 years ago. Not sure if the 10 or 9 speed will work or not. I would check with a good bike mechanic before buying just to be safe. I bought and older Specialized Warrior Sport that happened to have an 8-speed rear cassette (not sure of the brand of the derailleur) and I installed the bar end shifters and they work great and have made riding fun again.

yes, assuming you have 7 speed rear deraillure shifter and chain. The width of the cassette is usually the same, it's the width of the gears plus spacing between the gears that are different.
1945269
Yes, it is 8 speed, 9 speed, and 10 speed compatible with the correct spacers.

why would you want a 7 speed mega range freewheel on a 6 speed bike?the 7th oversized mega cog wont even be accesable with 6 speed shifters and derailleur,why not get a 6 speed mega freewheel(shimano MF-TZ20 tourney 14-34 tooth 6 speed),make sure your shifters and derailleur are mega compatable!!!!!!!

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.
