70's peugeot U08 build help
I rarely find a problem with bottom brakets. A UO-8 will have a nice steel spindle. Grease and go. An ultra-6 speed freewheel will fit no problem. The UO-8 has long chainstays. Cross chaining really isnt a problem so you have 12 usable gears. Keeping things simple on these old machines retains their character.
