    this might be a noob question, but...

    i am building my first singlespeed road bike. the bike (80's nishiki century) was originally an 18 speed, w/3 front chainrings. id like to use only the outer 52t ring. my question is, do spacers exist that will help the front ring line up with the rear cog? if not, what's a good method and what hardware should i use? any help/advice is much obliged. thanks.

    you may bet lucky... If yolu can, put the chain ring on the other side of the crank spider.

    the good news is that you can use regular washers for spacers

    the bad news is that you may need to redish your wheel.

    but its not so bad, you'll get practice truing a wheel.

    sheldon has the answers.

    If you went with a bolt on cog you'd have a lot of flexibility with the chainline. You'd just add a washer or take one out till it's perfect.

    Road triples usually have a 50-45-40 chainline, so the outer position probably isn't happening. You can move the 52 to the middle, but you will still need 3mm of spacers or a new bottom bracket. 3mm is a crapton of spacers and 20 year old road bottom brackets don't tend to be in the greatest shape, I would spring the $20 for a new bottom bracket unless you think the inner ring mounts aren't clearing by 3mm now. This requires some measuring and figgerin' that Sheldon explains pretty well.

    I ran into the same issue with my first conversion (nostalgic feelings wash over me as the music swells and the image dissolves into memory) I used 1/4" nuts as my spacers as opposed to washers and 1/4" stove bolts as opposed to the cam or chainring bolts. I used nylocks to secure the chainring and ground down theremaining bolts leaving one thread thickness on the exterior of the nylock. go get em boy!
