How easily could this replace a 5 sprocket freewheel? Is there any worry about chain size/ frame width?

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.

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 !

I put a five speed freewheel on mine...but I put a spacer on first. No problems. Not sure how thick the spacer is though.

Yes. If you are replacing yourself, you'll need a special tool and the use of a vice to remove the old freewheel. A bike shop will remove the old freewheel for typically a couple of $. Take a view on YouTube, there will a removal video. Also check chain length after you install new freewheel. (In case the new one has different size cogs..."gears")Good luck.

Should be a pretty standard bike chain. I would suggest removing and taking it to a local bike shop for replacement. You can probably just lubricate the chain and continue using it.

I do believe your present bike is also a 7 speed as is the freewheel your giving thought to purchasing. A special tool is needed to remove the current freewheel from your wheel. Best option, take your wheel and your new gears (freewheel) to a bike shop. They'll swap them out for a few bucks. Check the chain length after you replace the wheel. That freewheel is a good. I bought one myself. Ride safe. Have fun !

Yes you have to play around a little as i did. I switch out the sprockets on mine. That`s just that my chain is two links short, but it should work well. Remember i used my old sprockets, just clean and grease them.

The wheels have Presta valves. I'm not sure how many sprockets the freewheel will hold except that I have a 9 gear cassette on mine.

Your spindle length may differ slightly. I installed my crank set on the existing 123 mm spindle I was using and it was just a little long. It would have been serviceable with slight adjustment to the front derailleur. I change the spindle out to a 5 mm shorter one I had in stock (118 mm) and the chain line alignment was perfect (50 mm offset). I would suggest trying it on your existing if you can and change it later if needed. If you need to buy a new one for this install, go with what Shimano's installation doc specifies as it would be the closest. Good luck!

No you need a FreeWheel type sprocket 6,7,or 8 speed available here http://www.amazon.com/sprocket-bicycle-chain-complete-accessories/forum/Fx3UFVVOO3Q29FB/Tx2DIFYOFGFJTR6/1?_encoding=UTF8&asin;=B000AO9KUC&cdEmailView;=8b290b24-c1b7-4323-9388-0ac7910c1df6.Tx2DIFYOFGFJTR6&cdShowAnswer;=1&forceSignin;=1

I purchased this to use on a Tricycle conversion kit from Bicycle Designers. It was too wide to use on that. This conversion kit is actually a Sturmey-Archer 5sp hub. You can get the specs on the Sturmey Web site.

No. You have a freewheel, not a cassette style hub. It will be a 3 or 4 prong or shimano-style freewheel tool. Since the replacement will most likely need a different tool, I'd suggest just paying you're local shop $10 to remove.

You will not need a new chain if the number of sprockets in the cassette remain the same, across the 11-23 and 11-28That is; if your 11-23 has 10 sprockets or is for a 10 speed, and the 11-28 also has 10 sprockets then there is no need to change the chain. The rear derailleur will compensate.

The freewheel you need depends on what wheel you have. The freewheel doesn't generally need to be replaced with the cassette.

If the bike has a cassette hub then no ,but many cheaper scwhinns still ( at least till recently ) used freewheel hubs.IF it will fit you'll still need to lengthen chain some to accomodate the big stump pullin' gear . A little internet search will help you figure out whst kind of hub you have and how to lengthen the chain correctly . Good luck !

It should. Double check your bike's sprocket width and tooth spacing. You can just measure your old chain.

Hi. I did but I had to make sure that the crankset fit my bike. It depends upon how much wear if any on the chain and freewheel. I had stripped the pedal threads taking old one off because a previous owner didn't use proper cleaning methods. The new crankset works great and was a good replacement. If you do you homework it should just bolt right back on. Good luck and just take you time.

It certainly looks as though it would. Both are 7-speed freewheels of the same overall range. There might be some minor differences in the between cogs, but nothing that should prevent it from working well.
