Ricitius said:I commute 16 miles daily on my sweet KHS Sport mountain bicycle. Recently, I began hearing a harsh creaking noise each time I pedal. When I got home I checked and it turns out that there is a crack on one of the chainrings. I recently got a new BB since it cracked. It's a Shimano BB, the model number is UN73. I have a road crankset: Shimano Nexave; I was wondering what other road cranksets would fit my BB based on the crankset I have right now? The reason for a road crankset is that I don't have to pedal as much to get somewhere. I am thinking about getting a Shimano 105 Triple Crankset it's seems good, but I don't know if it'll fit my BB:

What do you think?
Oh, and here is my BB:

If it is just the chain ring that is cracked, that can be replaced for much cheaper than the whole crankset.
That crankset will NOT fit your BB. Your BB has a square taper spindle, whereas that 105 crankset requires a BB that is Shimano splined (also known as Octalink-be careful though as there is V1 and V2 Octalink and that 105 triple takes a 118.5mm V1).
High quality square-taper cranksets are not really made anymore except for by Campagnolo and they require a campy-tapered BB.
You need a crankset like this:

If you really do need a replacement square-taper crankset, you might be able to find something on eBay.
Again, if it is a chainring that you need, that should be easy to find and will cost $25-30 or less.
