could I use a shimano UN55 cup instead of the plastic one provided? I broke my old BB, but the cups are fine!

Absolutely, just make sure it's clean,(bb shell threads too) and the inside depth,(where the cup meets the cartridge body) is the same. grease threads, all-set. loosen drive-side(main body of bb) to get L. side cup well started, tighten drive side, then final tightening of left side. Not to insult, make sure the new bb is same length as old one. I've done it at least 5 time because of my dis-taste for those awful plastic cups.

yes, I did just that on one of my bikes. Just make sure it fits tight on the BB shell. Mine did and I felt a little more confident withit instead of the plastic.

I had a similar setup before switching over with no problems... BEST move I made was switching from the old to the UN55 Shimano BB...

It should but find some pictures of Hollowtech 2 bearings and see if they look like what you have already on your bike. I don't know if it can be retrofitted if you are using some other Bottom Bracket bearing setup. This crankset is an identical replacement for the crankset that came on my GT UltraTranseo. It came as a commuter bike but I think this crankset is commonly used on MTBs . Thats all I give you for advice right now. Dean

Bottom bracket installation requires specialized tools. So even if you are able to find the propper size BB you would still need to buy the tooling. That's not very cost effective for something you're only going to do one time. I would weigh out the cost of taking it to a bike shop against the price of a new bike. Good luck

I used this one: Shimano UN55 BB Square Taper Bottom Bracket (68x110mm)it is a 110mm length BB.

If the bottom bracket opening is exactly 2 inches across, then the cup set should work. To make this measurement, after removing the crank, bearing cones and bearings, also carefully remove the old hanger cups.

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.

there should be a label on the bottombraccet itself with all the specs on it. if you cant find the info on the specialized web site the simplest is to remove the bottom bracket and take the info from there.

How about Amazon??? Shimano PD-M737 SPD Cleat bolt (M5x11.5-mm) I bought some, they are an exact replacement.

Depends on the existing deraileur, things like long cage and shifter components being shimano compatible have to be there. Chain length may need to be addressed.

Did some quick Googling and it looks like the Shimano 10 Speed Dynasys components are not compatible with any other style/brands including Ultegra. They used to be but not any more. Just basing this off of research.

We bought the Shimano UN55 BB Square Taper Bottom Bracket 68X107mm to use with Origin8 Square Top Track/Single Speed Crankset - 170mm x 46T Square Taper White.

No questions are dumb. I use a Shimano BB UN 26 on my older road bike with this crank. So yep, sure is.

sorry forgot to add. don't throw away your original BB. keep it some place. that way you have the all the measurements when you need to change it again. i would not be able to remember the sizes i need for my bike.i went already through a few of these BB.(never pressure wash your bike that is the beginning of the end of all the bearings... it washes out all the grease)

BB is included and it's specific for this crankset. (Hollowtech II SM BB51) BB easily found by it's self for replacement. Comes with shim spacers for use with either 68mm or 73mm width threaded housings and a very easy install ;o)

Hi John, I'm not familiar with your particular model bike. I bought this for my wife's bike after she took a spill and broke her pelvis. As it turned out, I did have to buy a new seat post from a local bike shop (about $25) because her original seat had a different configuration under it. This seat is more of a "normal" attachment, but you would have to make that determination after you get it. You can always return it, but I'm pretty sure your local bike shop can provide you with the right attachment post if you need one.

Yes, its a 9/10 speed crankset. The bottom bracket is included. If your interested here's a link to ebay where you can find the same crankset including the bb tool for $100 Shimano FC-M590 Deore Hollowtech II Crankset (Black, 175-mm 48/36/26T 9 Speed). Hope it all works out for ya.
