If it's a one-piece crank, then no. If it's the common two-piece (like newer Schwinns), then the only way to know is measure, measure, measure. At a minimum you will need to take the pedals off to measure the spindle length.

My first suggestion is to read all the previous answers on the UN55 before you attempt to replace your bottombracket assembly. If you can remove the spindle, look to see if the specifications of the spindle are embossed on the spindle itself. For example, my Shimano spindle has specifications of 68 - 122.5 embossed on it, the smaller number is the bottom bracket bearing tube width and the larger number is the actual spindle length. Then select the UN55 sealed bearing BB that is the closest to your measurements.

Well, let me see. If your Schwinn has a conventional crankset connected by a conventional bottom bracket then the Shimano UN55 should work. back in the early days, 1950's and before, Schwinn used to build bikes with a one piece crank. The UN55 won't work on that type (unconventional) of crank. If your Schwinn originally came with a 2 piece crankset with square taper BB interface, the UN55 is correct for you. Now keep in mind that the UN55 X 68MM is designed for a roadbike bottom bracket shell width. If you're dealing with a mountain bike it will be 73MM BB shell width. Also you will need to know the correct spindle length, they vary in length according to what is attached to the crank, drive side. Single, double or triple chainrings. Hope this helps.

First, I don't know. I have found calling Shimano Customer Service line to be very helpful when I had the same question. But in my experience as long as the number of speeds is the same, and the largest/smallest sprocket size is the same, you should be OK. Again, you should call Shimano to confirm. It is based on the derailleur, and in my case, I discovered from Shimano customer service that I was able to keep my same derailleur when I made my switch.

I did not see the whole question earlier. The Sram 4 and Sram 5 may have a different shifting ratio. The Sram 4 has a different ratio than Shimano. I think the Sram 5 is the same as Shimano, so it may not work without other changes. I am sorry I didn't see the whole question (Amazon's fault) initially. Good luck.

You need to measure your handle bar diameter. Shims come with the riser stem so that it can accommodate a range from 26 to 31.8 mm diameter bars. It should work with most bikes. Regards Dave

It should work with any mounting system . It only provides a mounting point for the bike.

Should work. Im using a Shimano TZ20 6 Speed Freewheel on mine which fit perfectly, it should be the same other then it being a 6 speed instead of the 7.

Yes. That is the exact setup I am running after upgrading my classic Schwinn. Works great.

if it mounts the same it should work just fine. you will need to make the adjustments to how far in or out the cage will go. it was the tx55. this is a 7 speed at the most.

It will work with Shimano 3x7 front derail. Definitely index shift. I have this shifter and it works As good as more expensive models.

I had purchased a couple different "Ditca" freewheels and neither fit. I finally ordered a Shimano SF-1200 and it fit perfectly.

Works on my Shimano 9spd chain that I'm currently running on a Campy 8spd group. I'd say it'll work with SRAM.

This should work with any bike you want to put it on. It works best on a bike with indexed shimano components.

As long as you have a Shimano deraileur it should work. Make sure you get the 7-speed set for a 21-speed (3 front/7 rear)

The Shimano A050 only has 7 speeds for the rear sprocket. There is no shifter for the front sprocket. I bought this for my beach cruiser which only has a single blade sprocket on the crank and a 7 speed in the back.

I have mine mounted on a Trek 3500 with no issue. Not sure what the difference in frame would be but I would suspect that you would not have an issue

Yes, currently using it on Trek 7.2FX with 8speed. Works identical to the original Shimano C102.
