How should I fix my chainline?
I am almost finished with my first conversion.
The cog is approx 43mm from center and the chainring is approx 47mm from center. I want to bring the chainring in. Should I use a new, shorter spindle or chainring spacers? I assume if I use spacers, I'll need longer bolts - that seems the easiest route. The bike is a circa 80 Raleigh Capri.
My other option is to move the hub over by having more axle spacers on the non-drivetrain side (I've got 8mm total of spacers to work with... Would I then need to redish? I'm not planning to use a rear brake, but it IS a flip/flop so I'd render that option obsolete...
Is the bike safe to ride in the interim??

1. move your chainring closer to the frame ie: on the inside of a dual ring setup.
(if not then)
2. ***** get a shorter BB ******
3. use chainring bolt spacers, not recomeded for anything more than 2mm.

Yeah the chainring is on the inside already. It looks like I need a new spindle.
It might be a few weeks till I can get to Yellow Bike.
Can I go ahead and ride it in the meantime?!?!

I rode it around the block a few times. It ain't ninja, but it's not loud. I was just worried that it would throw the chain.
Thansk for the help!

5mm is no big deal. Usually doesn't even make much noise with a 3/32 chain. As was said before, the easiest way is to just move the ring to the inside position. If its already there, or the cranks don't have an inside position, get a shorter bb. 107mm usually works well. Just measure to make sure you won't have any chainring/chainstay clearance issues. You could get just a new spindle, but given the cheap price of the shimano un53 sealed bottom brackets, they seem like a better idea. So much easier to work with.

I've got the same setup... flip flop and raleigh capri. I ride it, but it's loud. I've been riding for a month, always meaning to go get spacers. I'm aslo squeezing my rear triangle so I need some axle spacers (I don't want to cold-set the triangle) I'm running 700x35c's so I can't move the wheel any side-to-side because of clearance (none).
It's stock bb, shimano ultegra cranks... I guess a new bb would probably be the best option for me, too.
Thanks for starting this thread!
