Any reason for you being so aggressive?!
BTW he was right in what he said, while you came up only with hot air and some stupid story about an Indian guy...
So, if you don't know what you're talking about, why bother and annoy others? Just for the sake of it?
Look... who was the one being annoying in the first place ?
Read through what I posted previously again, if you know somewhat the installation process is like, you should be able to catch the subtleties and cues. If you need to be fed the details then its probably better you get them from Youtube videos.
Basically he was quoting/ rehashing what everybody else was saying after realising his folly.
As for the Indian chap, go read up on Hercules bicycles and you'll probably understand why a guy who may have assembled 100,000 bikes over 30 years and not understand the least bit about the modern derailleur installation and its quirks.
Excellent post sedluk!
I have to give it sedluk to have the patience to post in detail here.
I just didn't want to feed the troll.
Its just a guideline that will work with some but NOT all chainring and cogset combinations. It will work well with a standard 39/53 and 12-25 setup. BUT ... try doing it on a 36/52 and 11-28 setup and you get into problems ...
You still need the "small-small" combination check for sufficient chain tension and the "big-big" combination check to check for sufficient chain length (and prevent unnecessary strain on the RD at extreme crossover) to be 100% sure.
