So I'm at the point in my conversion that I need to replace my vintage stock crank arm that doesn't allow me to switch out the chain ring, with more suitable ones. I found these on ebay, http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT
That's pretty much what I want, and I figure I can use it with the existing vintage bottom bracket I have on the bike now. Would there be any reason why I shouldn't get these? Thanks!
