I'm taking an old schwinn continental and making it into a single speed to be my husband's beater commuter bike.
1. The two front chainrings are 52 and 39. I was going to use the 52 and do a 52 - 17 front and back. Is this sensible? My husband likes a hard gear, but doesn't want to rip out his knees.
2. Spacers. Because the 52 front chain ring is the outside chainring, with the chain then run too far from teh frame? will I need spacers on the single speed freewheel?
3. I haven't yet gotten off the old freewheel, since it needed a freewheel remover tool I didn't have (Park tool FR 4). Once I remove the freewheel (the tool is coming in the mail), will the diameter of the freewheel threaded mount be standard? for instance, can I get a freewheel such as this http://www.treefortbikes.com/364_333...ompatible.html and just thread it in?
