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.

Replacing the crank set is really not that difficult. The hardest thing I think is deciding how much you want to spend. Crankset can cost up to $500 and more. If you are not changing the derailleurs, you probably need to get a crankset with the same number of chainring as the old one. check out this video "How To... Replace Your Crankset" on youtube . I'm sure there are other videos that can help. Good luck...

Check this link, which depicts a compatible freewheel: Shimano Tourney 7Spd 14-28T Freewheel

Okay, so it's not the model of the bicycle, it is the compatibility of the components that work together. So yes, if you have 3 chain rings in the front and 7 cassette or freewheel cogs in the rear, most likely it will work. However, there are other factors: derailleur (the mechanism that reacts to the pull or push of the shift pod to change "gears") ratio (Shimano is about 2:1 units in the shift mechanism, so you need a derailleur that has the same 2:1 pin/rivet/bolt unit ratio), or something in need of replacement or readjustment.

Well, what can I say to help, make a few phone calls to bicycle shops in your area. But as long as it relates to a seven shifting options for you, I can't see any problems. My old 1994 ROSS Mt. Olympus 21 speed mountain bike, it work for me. I replaced both shifters, the original ones just tired out, yet my derailleurs are still going strong today. My opinion, they work better how the shifter buttons relate on the handle bars. Once I got them lined up & running they work great. How was that?

The shifter I purchased was model TX30-7R for 7-disk free wheels (see photo to left). My shifter has 7 "gears". I imagine Shimano sells a 6 position shifter, too. Was that the model you saw? Mike

Yes. Those are the ones on my bike. But your derailers might have a different ratio and that could cause incosistancies when shifting.

The right shifter shifts the rear wheel sprocket. In my case that is 7 gears. The left shifts the crank sprocket. in my case that is 2 gears. My rear brake is connected to the right brake lever and the front brake is connected to the left break lever. The small levers shifts up and flipping the brake lever in towards the center shifts down. I put these on my 14 speed Schwinn and they work very well. I also changed my rear sprocket and change and in it amazing how much better the bike is. I love mine and hope this helps. Happy Riding.

Yes you could use that crank it will work. You will need a new bottom bracket. And your gearing will change

NO! Absolutely not! This is a SRAM 1:1 pull ratio shifter that works with SRAM 1:1 ratio rear derailleurs NOT SHIMANO!!!!! It will work with a SRAM rear derailleur & a shimano cassette but NOT THE OTHER WAY AROUND. Period.

If you're derailleur is a shimano tourney this should work fine without a longer chain. The freewheel tool for the removal of the old freewheel is the only tool you'll need.

NO! No, it will not work. The SRAM shifters only work with SRAM rear derailieurs, because the ratio is 1:1 vs Shimano 2:1. The front derailieurs for both systems are interchangeable as they use the same ratio.

Hi, You will need to purchase a 5 speed shifter. Because these are specified as seven speed (rear). A 5 speed shifter will only work with a 5 speed cassette. Thank you.

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.

Yes. It will work fine. The front deraillure is no problem. You can run whatever front deraillure you want. For example, on my sons bike we have x4 shifters with a shimano slx front deraillure and a SRAM x5 rear deraillure. Their X... lineup components are all interchangeable. You just need to make sure you run SRAM shifters with SRAM rear deraillures. The front deraillure can be whatever you want. Even their road and mountain bike stuff works together. My bike is s mix of SRAM mountain bike (x9) and road bike (rival) components and I have no issues.

No I believe you can't. You need to use shifters with the same gear ratio that your bike is configured with in order for them to work properly

Years ago I had a 5 speed and upgraded to a 7 speed. The new freewheel should screw on no problem. Although....... The rear wheel will most likely need yo be "re-dished". Meaning....... The rear hub will need to be shifted on the axle to the left to accommodate the additional gears. That will offset the rim and will not be "centered". It will then need to be centered. 'Re-dished". You might need a new chain, depending whether you present chain is long enough. New chain ? About $10.00. The re-dish might run $15.00 to $20.00. This will be needed to be dona at a bike shop. My suggestion..... 1. Call a bike shop first and explain what you want to do. They will be familiar with the situation. 2. You will also need a special tool to remove the old freewheel. The bike shop will have it will make the swap when you bring them you wheel and new freewheel. Call the shop before the purchase. The freewheel is a great price. Two extra gears will be nice. I would certainly do it. Good luck. Enjoy the ride !
