|I took my 1996 Bontrager Race frame that was hanging in the garage and stripped & painted it and built it up as a single speed. I already had most of the parts so the total cost was pretty reasonable.
Remove headset cups $11.97
Paint stripper, primer, paint and clear coat $26.94
Chase BB threads & reinstall headset cups $18.50
New chainring bolts $5.98
PVC spacer $3.02
New brake cables $4.33
New bar ends $10.87
I set it up with 42/15 gearing for now since that gearing combined with my chainstay length is supposed to work out to an even chain length precluding the use of a chain tensioner. It's not too bad, but it would be nice if I could get the chain just a tad tighter. Would it be a bad thing to file 1/4" out of my drop outs to achieve a tighter chain?

|I've had problems filing dropouts. I broke a Vitus frame after I filed about an 1/8". If you go with a 16t cog, You'll gain another 1/8". I'd try that first. 42/16 is what I run on all my SS's.|
|May have been a fragile part of the Vitus.||dzrider|

|I broke the derailleur hanger on mine trying to shift back onto the large chain ring after throwing the chain. That being said, I like your 42x16 plan better than filing.|
|Looks like I need about a 1/16th||B2|

Thanks for the suggestion. I just tried the 16T cog and I can get it in the drop, but man is it TIGHT!
After hearing your experience with filing, I'm not sure I want to go there, but I only need a LITTLE BIT. I'll have to comtemplate that one for a while before I take the plunge.... and I really think the 42/16 would be closer to what I'm looking for.

|Don't file the dropout. File a flat spot on the axle. You should be able to safely get 1/16". Sheldon Brown has a description of that on the Harris website. He even describes filing the entire axle flat with the lockwasher to allow some adjustment.|

|Also check out the White Industries hub at sheldonbrown.com, might be worth the $$ in a few months if you get hooked on SS/FG riding....|

|I recall that this came up before and that there was somewhere that you could get a half chain link to fine tune your chain length. Anybody remember?|
|Half link?||eddie m|

|I've seen half links for industrtial chains, but I don't know if I've ever seen one for any 1/2 pitch chain. You might try the McMaster's catalogue or other industrial supply catalogues. If you use a half link and a little filing as above, there should be lots of conbinations that would work.|
|Messed my hub up?||B2|

|Well I filed the axles and ended up the perfect chain tension. However in the process, when I inserted the wheel into the drops prior to filing the axles I think I may have "tweeked" the hub. The freewheel (coasting) noise sounds normal, but when I pedal, it just doesn't sound right. Hard to describe, but I can tell you that it makes a pretty good racket.
If I applied too much pressure on the hub by forcing it into the drop outs with too tight a chain, will an overhaul remedy the situation? What components will I likely have to replace? I have to admit, I don't know much about hubs. I'ved dinked around with just about everything else and feel pretty comfortable with repairs and adjustments on everything except hubs.

|Unless you have a perfect chainline and your gear is perfectly true, then your chain might be very tight in only one little spot and not in the rest.
As for half-links go I use them, they DO make 1/8 half link and ive heard of a 3/32 half link for tandems, but dont know anything about them.
Get yourself a 1/8 KMC chain and a half link should solve any problems and its safer then altering dropouts or axles.
I ran into too many problems when I filed my axles and dropouts....I dont wanna talk about it thought it was a bad experience.
you should put some drop bars on that thing...or some moustach bars would be a good compromise.
