I spent a couple of days reading through all posts regarding chain-line issues prior to this post, so hopefully its not too redundant.

I suspect that the chain line on my khs 03 flite 100 is a bit off. Anyone else having this issue? apparently its common on the bianchi pistas (at least the past couple years).

here is the longer story:
It was making the tank tread noise at one point. After talking to a fixie guy at a shop i thought it was bc my chain was too tight. I also thought it was an issue with my stock wheel. the freewheel side seemed to be ok but the fixed seemed a bit off.

So after striping the stock fixed hub i had a wheel built - phil w/ deep v. I had the shop switch over the cog and tire, part to make sure everything was tightened right (and avoid striping the hub from user error) and everything lined up right and part laziness (i hate changing tires/tubes).

Well the put the wheel on tighter than i have ever had it. It wouldn't hardly spin around if i moved the pedals with the bike lifted up. It rode worse than my old stock hub and made way more noise (tank tread type). This was about 5 days ago.

So this weekend replaced the armadillos i was starting to hate, making a point of not putting the week back on too tight. side note --The phil hub is MUCH easier to get on tight and straight vs my old hubs. Even after several adjustments its still seems to be making noise. The chain seems to be getting hung up a bit on the bottom of the cog, on the last tooth before it goes straight and off the cog.

I am thinking this is potentially normal or acceptable, but likely an alignment or chain issue. I am planning on giving the chain a good lube this week to see that makes a difference.

I should also note that is an 2003 but i got it end of summer/fall of 2004. so its less than a year old and sat inside 3 months during the winter. so still basically new.

i can pics if it helps but, i was mainly wondering if others had a similar experience so i don't think i'm just getting overly obsessive about my chain line.

If you want to know for sure how good your chainline is then get a (good) vernier caliper and measure it.
A=width of seat tube
B=width of chainring
C=distance from far side of seat tube to outside of chainring
D=width of hub (outside flange to outside flange)
E=width of cog
F=distance from outside (driveside) flange to inside of cog
C-((A+B)/2)=F+((D+E)/2)? If so, perfect chainline. If it's off by a mm or less, it's close enough.

I've got a pretty good chainline on my ride (almost exactly 1mm off), and it still makes a lot of noise sometimes. I've been thinking that the solution is to get a better chain.

I have a 2005 KHS, I also have tank chain syndrome but I suspect that mine is because the right dropout is slightly bent....the rear wheel will center under the chainstay bridge but then it's offset under the brake bridge. If I center under the brake bridge, it's off under the chainstay bridge. Go figure...

Sounds like mabye a bent axle Krazie?
