All the old, state owned breweries were sold to foreign big breweries (Amstel, Heineken etc). Now all the Serbian beers taste the same - worse than they used to. Not to bad, but not as good as they used to be. However, there are a few decend ones still being made in the south-middern part of the country.

This one is good:

Zaje?arsko pivo - Wikipedia, the free encyclopedia

But only the batch that is produced (and sold) in the southern part of the country.

ok ... just adjusted the position of the rear wheel to take up the chain slack.

it's now at the limit of threads on the chain tugs ... let's see if I can get another 1000km out of the chain or so.

this is how far the chain has stretched ...

opinions/suggestions/comments?





edit: i guess at some point, i can take a link out of the chain and slide the wheel forward to get some more use out of the original equipment. in other words, that would bring the rear wheel position back into the adjustment range of the chain tugs? i assume that would allow the rear wheel the slide foward by the link length/2? does that make sense?

Aha wish I'd checked in sooner but you figured it yourself. I'd suggest changing out the chain soon though...

why?

i can't imagine that's much stretch

i would estimate around .8cm or about .31 inches

now to figure out how many links I have with a 44/16 ratio?

http://eehouse.org/fixin/formfmu.php

according to that website with a 44x16 ratio and 41" chainstay ... I need roughly 85 links

so, it seems that i've stretch roughly .31 inches over 42.5 links or about 0.087 inches over 12 links

is that bad?

You could always ditch the chain tugs, too. It's pretty easy to cinch the wheel in place without them.

I was working on the assumption you'd started at the inside of the track end and it had stretched far enough back that the tugs were no longer helpful, from what you're saying your wheel started much further out in the track ends?

To give you an idea, some schools of thought say change your chain at 0.5% which is 0.0025 inch per link, that's more like 1/16th inch over 12 links if you want the easier route. Seems silly yes, but since chainstretch is just the rollers wearing down on your chain, they can then prematurely wear down your cog and chainring as well.

interesting ... seems like a lot of wear for only 700 miles or so?

let's see how it goes.

Does seem excessive I agree, but I dug this up from SB for you.

"
  • If the link pin is less than 1/16" past the mark, all is well.
  • If the link pin is 1/16" past the mark, you should replace the chain, but the sprockets are probably undamaged.
  • If the link pin is 1/8" past the mark, you have left it too long, and the sprockets (at least the favorite ones) will be too badly worn. If you replace a chain at the 1/8" point, without replacing the sprockets, it may run OK and not skip, but the worn sprockets will cause the new chain to wear much faster than it should, until it catches up with the wear state of the sprockets.
  • If the link pin is past the 1/8" mark, a new chain will almost certainly skip on the worn sprockets, especially the smaller ones."
  • Chain Maintenance

maybe i'll just run it until it breaks and then change the ratios (44/16) to something more interesting as the commute is flat and i'd like a little more speed as 100rpm gets me only an average of 34.4km/h (21.5mph)

There's a few hills here but the fixed gear I ride the most is 52x16 and it's pretty fun, I've considered getting a smaller cog.

The weather is starting to get nice, so I can see everyone's attitudes changing and they're becoming more pleasant. They're also starting to shed some of the layers of wool, which is always nice since I spend most of my time on a university campus...

booked my first fun ride on the bike (to MiMA):

mima ? welcome to mima - mima ? welcome to mima

MiMA si super small, but quite well done.

40km (25miles) ... I guess I need to take that into account when calculating the cost recovery compared to the bus (so don't let me forget!)

lol ... i have a grasp at how chain stretch works.

i didn't expect it to be noticeable. i mash up a reasonable large hill at the beginning of my ride everyday and I'm sure this doesn't help :/

Are you sure the wheel is not being pulled forward in the axle slots?
