The cranksets that used a bottom bracket spindle lenghth of 122.5 were quite common in the earlier versions of Shimano’s mountain series of triples, (XT, LX,DX, etc) of the late 1980's utill the early 90's. The XT line was considered the “best” prior to the release the XTR series. The vintages of these series utilize the “Full” size chainrings that are the same size that you have now verses the compact series that were introduced around the mid 90’s and are more common on higher end rides today
If you take a look at Sheldon Brown’s bottom bracket guide, you can see what cranksets use a 122.5 bottom bracket. Link is HERE
Keep in mind, should you decide to change to a different series (configuration wise) of crankset, you may find that you will have to change the bottom bracket and the front derailleur as well. All of these components are meant to play nicely with each other.
You can find NOS (New-Old-Stock) versions of these once great cranksets often on EBay among others. These series are perfect for a current Hybrid application
