Chain question

[alexg]

Hello All, I found out this afternoon that my chain slack is approximately 1.5cm but in two places it is 2.2cm, is it still ok to have that much difference in slack or it is recommended to replace the chain. Also, can you please provide chain specs and maybe recommendation of some not expensive (under $50) and durable chain so I can buy it and keep it under the seaa just in case.
Thanks.

Do you mean 1.5 inches?  1.5 Centimeters would make your chain a bit tight.  It should be .8 to 1.2 inches.

Yes, centimeters, but I used my eye judgement, is it really too tight? I will use tape measure tomorrow morning to take exact measurements, how much is it recommended to be?

1/2 inch chain slack is 1.27 cm so it's alright chain slack. But yes it's pretty normal for chains to have loose spots or uneven wear as they age. The real test for worn out chains is pulling on a section of links while it's on the rear sprocket, if it pulls off more than 1/4 links worth of chain, near abouts 1/8 inch, then your chain is worn out.
