Single Speed- Bike Chain at Angle
I have a Raleigh Super Grand Prix converted to single speed.
The question i have is that the crankset i have comes out a bit from the bike so the chain goes to the freewheel at an angle.
Is this normal, or ok?
Is there a way to fix it, or do i even need to? Basically i am trying to find out if i am really losing any power.
Thanks

it's pretty normal actually.... it can cost some loss of power depending on how bad it is... depending on your frame size/hub size you could straighten it out with some axle spacers, but if you don't have them already i dunno if they'll fit in there.

Is the chainring on the inside of the crank spiders? If so, you may need to move some spacers around on the rear axle to get it right.

If the angle is bad enough for you to comment on it, I would think it needs to be fixed. A picture of it would help us though.
You either have to move the location of the freewheel out back or move the location of the chainring up front. For the first, this means respacing and redishing the wheel. Or, if the freewheel is assymetrical, flipping it around. For the second, this could mean putting the ring on the other side of the spider arms, using spacers between the spider and ring, flipping the spindle around (if it is assymetrical), or using a different length spindle.
