OK. I ride a Flying Pigeon . I live in China. For those not familiar with FPs, they are very similar to old Raleighs and have horizontal drop outs.
I just installed a 3 speed gear hub and there is drag on the pedals. Sturmey archer manual says that the cause of drag on the pedals is un-parallel chainstays.
It does take an amount of effort to squeeze the chainstay to the point where I could bolt up the hub axle. Of course that changes the angle
So here is the question:
1. How do I know I have unparallel chain stays?<br />
2. Is parallel measured before or after reassembly?<br />
3. If they are unparallel what do I do about it? This is the way the bike is made.<br />
4. Is there any other possible cause for this dragging, like an over tight chain?<br />
5. How would I loosen the chain?
