For either 68 or 73mm shells with included spacers. BB is included with this set and is specific. (Hollowtech II)

This crankset comes with a hollow style BB. There is a special tool that has the correct tooth profile, but I just used a strap wrench to tighten the cup in place. Its always a good idea to chase the BB threads with the correct tap, or have a local bike shop do it. After maybe 50 off road miles, I had a breakdown, but from my rear derailleur. While I had the bike apart I noticed the cranks were turning smoothly, but not freespinning, like there was some seal friction, so it may be wiser to either use a torque wrench to adjust/tighten the BB cups. Shimano always gives very specific instructions, so thats a plus. This crankset comes with a hollow style BB.

Yes, we have the crank style too and it works just fine. I bought 2 of them.

Check your old one. 97.2% of the time it's written right on the bracket cartridge unless your builder really cheaped out. OR If it's a new build it's based on what the crank calls for. The paperwork with the crank will tell you what you'd need for a proper chainline.

Yes, this will work. However that crankset already comes with a bottom bracket.

It is for the cranks only (both left and right). Of course, you'll need the bottom bracket and the pedals.

There are different bcd (bolt circle diameter) for different cranks. If yours is a four bolt pattern it is most likely a 74 bcd and this one would work. However, there are many five bolt patterns such as 110 for compact road and 130 for standard road. So find the bcd for your cranks and you will have your answer.

It's been quite a while, but I think I used the bolts from my existing bottom bracket. If you are getting a new BB it should come with bolts. If not, they are easy to get.

bottom bracket must measure 123mm from one end of the spindle to the other end

Does it have a one piece, or three piece crank? Also a model name, or number would be helpful

I can't say specifically. you need to measure the width of your bottom bracket. many sizes are available

The bearings consist of two sealed cups that thread into the bottom bracket on each side. The crank is attached to a hollow shaft that slides through these cups. This design is called Hollowtech II by Shimano. I'm not sure about the width, as it may work for a range of widths. I used this to replace a 68 mm English threaded BB on my 2008 Specialized Hard Rock XC Disk and it worked out well. It comes with plastic spacers that allow you to adjust the chainline (distance between the seat tube center and middle chainring). I believe all of the spacers must be used, but you shift the cranks side to side by changing the number of spacers under each bearing cup.

I thought it was a weird question until I looked up "Bb68 73" and found this...Shimano XT SM-BB70 Hollowtech II Bottom BracketLooking at the pictures on the left...Now that's weird.

This is for the old style American bottom bracket for single piece crank sets like the 1979s Schwinn type 10 speeds.

Sorry, I can't find a record of my Bottom Bracket order but would recommend checking out this page for advice. http://sheldonbrown.com/bbsize.html

I think the tool you are referring to is the FC 16 which is a plastic piece to do one side of the crank. The tool that is what you really need is the Park BBT 9 or the Shimano TL- FC 32. I have the BB 9 and it made the job a breeze. Bob

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
