Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Conversion Pictures and a Question

This is my dad's old Fuji Del Rey that i made into a fixed last weekend. It is what i use for going from class to class around campus.





Im wondering how i could fix my chainline, because right now i have it on the smaller chainring, i couldnt get the largest chainring to line up as you can see in the picture it is really far off. Would spacers alone be enough to fix that distance?





Also, if i use the larger chainring and remove the smaller one, ill be running at something like 52/17. im not sure if i could use that.

As you might see, the wheels are not matching. i bought a formula flip flop hub, the rims and hub are what come on the Giant Bowery Fixed gear bikes. Once i get some more cash ill get the matching front wheel, and put a set of bullhorns on it.


Thanks

a few ways to fix your chainline so that you could use the outer ring would be to:
-get a shorter or adjustable bottom bracket that would bring your driveside crankarm in a bit (you will have to check to see if yor chainrings will clear your chainstay)
-run your big chainring on the inside of the spider (would require new chainring bolts and would still depend on if your frame has clearance to run that big of a ring on the inside
-respace the rear hub so that the cog lines up better with the bigger chainring and then redish the wheel so that the rim is centered (not super hard, but more involved than a new BB or new cog/chainring)

i have no experience with spacers for the cog so i'll leave that to someone else

42/17 is a more normal gear ratio than 52/17 for most people, especially beginners. i'd suggest keeping it like you have it for a while. If you feel like your are spinning too much, you can get a smaller cog (14,15,16) or a mid size ring (44-49).

I dont think the top ring is removeable so you cant run it in the smaller ring's place. You could flip the axle in the bottom bracket for a better chainline. Or just get better cranks.
