I have a Schwinn hybrid with 7 speed shimano freewheel and rear derailleur... no front shifter. Can I replace crankset with these?

They will if the bottom bracket is a four sided shaft. Nice set for the $, light also.

You might want to go to YouTube and enter "Freewheel Replacement". There are a number of videos that explain the process. You will need a Shimano freewheel removal tool that you can get online or at a bike shop.

Off hand I will say yes, assuming that your current crankset is of comparable value and the spindle is of the square, tapered type. I can be more helpful if you tell me what your current crankset is and from what bicycle.

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

This crankset should pair with your shifters as long as you have a triple crankset and not a double.

Make sure that the capacity of this derailleur meets your requirements for the big cog. Other than that, new shifter (only need one since you're eliminating the front derailleur), new cassette (if you're on a 3x8 there is a chance you have a free wheel vs a free hub in which case you may need a new rear wheel. If your crank isn't serviceable (I.e. Riveted chainring vs. bolted, you will need a new crank and possibly a new bottom bracket if the chain line is changing. Usually a good idea to run a chain guide on the 1x also, even though this derailleur pulls tight and doesn't bounce much at all (maybe replace defunct chainring with guide?). Sounds like a fun project, enjoy! Make sure that the capacity of this derailleur meets your requirements for the big cog.

Yes you need a rear derailleur hanger. Yes this will work with a 44T front crank chainring, the shimano crank set I paired this with was a 22, 32 44T, however I ended up taking the 44 off and replacing it with a bash guard. The largest you can go on the cassette is 36T.

Yes, you just have to adjust the screws on the front derailleur so the left shifter do not go pass two.

You can use the newer version provided the gearing is the same. I used this Sora to replace a Shimano shifter from the 90s so I am sure it would be fine to upgrade an older version of Sora (again, provided you are using the same number of cogs on you front crank and rear cassette).

Yes, if your bike has disc brakes and a cassette hub (as opposed to a freewheel hub). If you don't know what you have, take the bike to a bike mechanic - he/she will not charge you anything to tell you what you need.

You could use this shifter, but there is probably a 3x6 set available. See the Shimano SL-TX30 set on Amazon which is for an 18 speed bike.

if your bike is 7 vel. you're not going to have any kind of problem. just mount your freewheel, and ready to run. if maybe a little adjustment with small screws having the deraileur you can fix is needed. I hope you solve Manny

The main thing is, SRAM REAR derailleurs will only work with SRAM REAR shifters, and vice versa. You can never use SRAM with Shimano in the back. It doesn't matter in the front.

I believe the photo is errant. What I received was a 7 speed. You definitely don't want to substitute an 8 speed on a 7 speed application. You'd have too much slack in the shifter cable (in position 8 on shifter) even if you adjusted the deraileur stops to avoid the chain falling off, and an annoying dead spot gathering up that slack when shifting back into the lower gears.

It depends on your chain, the brand and and how old that 7 speed cassette is. The width of chains have changed over time and just installing new gears can be problematic as a consequence of both the change in chain link sizes as well as the consequent changes in derailleurs. Hard to say. It will probably work in a pinch but the only way to be sure that your entire drivetrain works in harmony, you kinda need a complete set (cassette, chain, chainrings and sometimes even derailleurs and shifters if you're changing component generations).

Not familiar with that bike, but these shifters are very adaptable. The shop where you purchased your wheels should be able to confirm these shifters as being appropriate for your machine. Good luck!
