I acquired this little gem from the local thrift shop and it's got a delightful ride. the bottom bracket's loose, and of course I don't have the correct size crank pulling tool for it, but I think I may have a hard time parting with it once I've gotten it cleaned up and dialed in. Meanwhile, I found that the Simplex front derailleur's rubber bracket has cracked. I'll have to scout out a replacement.

Oh, and what size is the Allen wrench for the stem bolt?
