So I've got this old Free Spirit I'm converting over to a fixie (I know I know, free spirits suck,) and I need to get the crank off but for the life of me I can't figure out how. Any help would be appreciated.
too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
That's an Ashtabula crank, or a knock off of one. They were SOP on American bikes for decades, then relegated to juvinile and BMX bikes only. yor remove them by removing the large lock nut cone on the left side of the crank/bottom bracket, then snaking it out to the right. Be sure to remove the pedals first, otherwise you'll be up the creek.
You can save yourself some dough by looking for an SS or BMX chainring to fit the crank (they're very common) and keeping it in service. The BB is very simple to service and durable.
thanks guys, figured it out just a minute ago. it needed to be cleaned anyway, the bearings look like hell and it's all kinds of nasty in there. I've got a brand new spare chain just needs to sized I reckon.
