Just got the Shimano cranks today in the mail from ebay purchase for a good price so a $24 Shimano UN54 w/ 118mm length will be purchased tomorrow.
Kinda sucks since that's more than I paid for the crank.
Oh well, the Suntour BB and Sprint crank will go in a drawer for now. It's a 170mm. Not sure why they outfitted the bike with 170's in 1988.
Schwinn put 165mm cranks on smaller frames.
The cranks are great just too short for me.
Thanks for the help guys.
