I bought this wheel for $30 off someone who knew even less about fixies than i do.. did I buy the right thing lol? I assumed it was fine but then on Sheldon's site he mentioned that there is a 2nd kind which is apparently the "wrong" kind?
mine does have smaller threads on it...BMX type...BMX flip-flop hubs have two different freewheel threads, a standard one on one side, and a special smaller-diameter freewheel thread on the other, designed to work with special small freewheels (14, 15 teeth.) These are now quite rare, but if you are calling around looking for "flip-flop" hubs, make sure you get the right kind.
side a with big and small threads
side b, just big threads
so, assuming it's the right kind of wheel, to make just a fixed gear I just need a cog and a lockring right? and to add a freewheel i need to buy a freewheel and another cog? or does the cog come combine with the freewheel?
also, how do you determine what gear to put on? I'm assuming you use the gear calculator tool?
I was using that but I wasn't 100% what my chainstay length is and how adjustable my drop outs are. When the wheel is all they way in the drop outs, the measurement from crankbolt to wheel axle bolt is 43.5 cm, so i guess i can adjust it in like maybe .25cm and still be safe?
I'm just gonna use my existing 42t or 52t chainrings for now.. not sure how good of options that leaves me. the bike i'm converting isn't made for speed so i'd rather just have it geared for "cruising" .. i had it in a good gear the other day and didn't need to shift.. ill have to see what it was.
